Polymer dielectrics having low dielectric constants are necessary for next-generation package substrates to achieve lower losses and higher bandwidth densities. Conventional silica-filled dielectrics have higher dielectric constants due to the silica fillers. Therefore, it is important to explore novel dielectric materials for next-generation package substrates that have lower dielectric constants. Parylenes have a unique set of properties such as- very low moisture absorption, low gas permeability, conformal deposition, and heat resistance. Some parylenes also have a very low dielectric constant, low dielectric dissipation losses and low roughness that make them attractive as dielectrics for application in advanced package substrates. Amongst all parylenes, Parylene-Hthas the lowest dielectric constant $(\mathrm{D}_{k})$ of 2.17 and dissipation factor $(\mathbf{D}_{f})$ of 0.001 at 1 MHz, thus making it attractive for high-frequency applications. However, there are several challenges associated with the use of polymer dielectrics in package substrates such as- adhesion to Cu, via formation ability, processability, mechanical reliability and electrical reliability. This paper evaluates Parylene- Htwith respect to all these challenges.

The importance of silicon cannot be undermined - in photovoltaics (PV) as well as in semiconductor industries. However, silicon is very brittle. Silicon cells/wafers crack easily during manufacturing assembly and/or during device operations. Crack Catcher AI uses novel smart fracture mechanics approach with Artificial Intelligence (AI) methodologies to predict and control crack/damage evolution in thin silicon cells/wafers. This is critical as semiconductor 3D integration technology calls for wafer-to-wafer bonding with utmost alignment accuracy and yield/reliability. © 2025 IEEE.

Providing enhanced quality of service (QoS) to support demanding applications in the most energy-efficient way has been identified as a primary objective of future 6G networks. Towards this direction, the concept of programmable wireless environments (PWEs) has emerged, wherein extremely high QoS can be ensured by controlling the wireless propagation through reconfigurable intelligent surfaces (RIS). To meet the demands of 6G networks in terms of energy efficiency, in this paper, zero-energy RISs (ZERISs) are introduced, which harvest the required amount of energy for their operation and then contribute to the PWE conversion. More specifically, we investigate the performance of a ZERIS-assisted communication system in terms of joint energy-data rate outage probability, which quantifies the trade-off between the harvested energy and information transmission, for three distinct simultaneous wireless information and power transfer (SWIPT) methods are investigated, namely power splitting, time switching, and element splitting. Finally, simulation results validate the derived analysis, leading to useful insights for the ZERIS-assisted network regarding which energy harvesting method achieves better performance in terms of joint energy-data rate outage probability.

Solid-state circuit breakers (SSCBs) have gained traction in the protection field due to their fast fault interruption and arcless operation. This paper proposes an improved fault current bypass-based DC SSCB for DC microgrids. The proposed topology features fast fault isolation and cost-effectiveness. Initially, the superiority of the proposed topology is analyzed in comparison to two prior-art fault current bypass-based topologies. Next, the operating principles and key design considerations are presented for the proposed topology. Finally, the effectiveness of the proposed topology is verified through both simulation and experimental results. The proposed topology is the most cost-effective solution, with 99.82% efficiency and a 15% cost reduction for power semiconductor selection compared to the other two traditional fault current bypass-based topologies. Experimental results from a 400 VDC/80 A prototype demonstrate the feasibility of the proposed topology, showing that the clamping voltage of the metal oxide varistor (MOV) is lower than the DC voltage.

In classical works on a planar differential pursuit-evasion game with a faster pursuer, the intercept point resulting from the equilibrium strategies lies on the Apollonius circle. This property was exploited for the construction of the equilibrium strategies for two faster pursuers against one evader. Extensions for planar multiple-pursuer single-evader scenarios have been considered. We study a pursuit-evasion game on a sphere and the relation of the equilibrium intercept point to the Apollonius domain on the sphere. The domain is a generalization of the planar Apollonius circle set. We find a condition resulting in the intercept point belonging to the Apollonius domain, which is the characteristic of the planar game solution. Finally, we use this characteristic to discuss pursuit and evasion strategies in the context of two pursuers and a single slower evader on the sphere and illustrate it using numerical *** Codes 58E10, 86A30, 37D40, 91A23, 49L12, 49Q10 © 2024, CC BY-NC-ND.

In recent years, speech enhancement in the presence of very harsh noise has received a lot of attention. In this paper, an adaptive noise canceller (ANC) having a single-reference and multi-primary channels (SRMP) is introduced to recover the speech signal from its contaminated measurements. This SRMPANC takes a bone-conducted (BC) signal as its reference and adopts multiple noisy air-conducted (AC) speech measurements as its primary signals. The multiple primary channels are connected by a linear combiner (LC) which is optimized and updated by a recursive least square (RLS) algorithm. A linear or a nonlinear filter (e.g. FIR, Volterra, etc.) is equipped in the SRMP-ANC, that is updated by an LMS or LMS-like algorithm. Extensive simulations with real bone-and air-conducted speech measurements are performed to demonstrate the effectiveness of the proposed SRMP-ANC. It is revealed that the speech recovery quality is significantly improved as the number of primary channels is increased in terms of both mutual correlation and mean square error (MSE) between the AC speech signal and its recovered version. © 2022 IEEE.

Ising machines (IMs) are hardware solvers designed to tackle computationally complex combinatorial optimization problems (COPs), harnessing physical processes such as quantum annealing to simulate the Ising model, enabling these specially designed solvers to tackle a wide range of computationally complex NP-hard problems in real-world applications, such as portfolio optimization and logistics planning. While prior works propose to fabricate dedicated integrated circuits for building IMs, we leverage off-the-shelf Graphics Processing Unit (GPU) chips for implementing Ising algorithms for quick development. In this work, we explore parallel tempering (PT), an Ising algorithm, which shows promise owing to its capability for parallel processing of multiple independent searches for the optimal solution, each with a different amount of randomness that allows escaping local minima. We propose several optimization strategies, including addressing the dependency problem in PT to enhance algorithm parallelism and integrating genetic algorithm (GA)-like operations to increase the diversity of the search process for effective solution discovery. Empirical evaluations demonstrate that our proposed Parallel Quantum-inspired Search (PQS) solver achieves a $2.66 \times$ speedup over the state-of-the-art GPU-based solution without sacrificing solution quality.

Social assistive robots usually encompass a great compromise between the advanced perception models that one can use and their computing capabilities. The ideal approaches are always oriented towards low power consumption while maintaining a higher order of responsiveness to the surroundings. Therefore, we present in this paper, an improvement of the follow-me system on ASTRO. In detail, we propose the use of Mediapipe SDK for human detection and tracking, when ASTRO is meant to accompany someone that is walking. A study on the new velocity and distance profiles that the robot keeps from the individuals is presented and we have also evaluated how it affects their perception of being safe. The presented results show that our new approach allows the system to achieve real-time performance by becoming $\approx 9.1\times \mathbf{faster}$ , smoothing, and keeping a more natural distance from the user.

This study proposed an interlinked coupled split square ring resonator (SSRR) based metamaterial (MTM) unit cell. The double-negative (DNG) metamaterial characteristics are exhibited in C, X, and Ku microwave frequency bands. The proposed MTM unit cell contains six split square ring resonators (SSRR) where a horizontal metal bar is interlinked between the fourth and fifth SSRR and a vertical metal bar interlinks between the third and fifth SSRR. The perfect electric conductor (PEC) and Rogers-RT 5880 are used in the resonator and dielectric layer to design the MTM unit cell. The unit cell has a dimension of 10×10×1.57 mm3, and the thickness of the resonator layer and dielectric layer is 0.04 mm, 1.57 mm, respectively. The computer Simulation technology (CST Microwave Studio 2019) software is used to extract effective parameters then the finite element method (FEM) is used to verify the unit cell's performance. Due to symmetrical structure, negative permittivity, negative permeability, and negative refractive are achieved. As a result, the proposed unit cell can improve microwave devices' performance for C, X, and Ku bands, particularly satellite and radar communications. © 2021 IEEE.

This paper develops a cost-effective and accurate procedure for parasitic capacitance extraction for three-level neutral-point-clamped (3L-NPC) inverter modules. Compared to traditional methods, which require full system measurements or open-module configuration to obtain the module parasitic capacitances, this paper simply estimate the parasitic capacitances from the ringing frequency of the common mode (CM) current in the proposed extended double pulse test (eDPT) setup. The proposed analytical method has been verified and compared with the traditional open-module measurement results. The extracted parasitic capacitances have also been used in the CM electromagnetic interference (EMI) model and show good accuracy in predicting the CM noise spectrum compared to the experimental results from a three-phase inverter-filter test bed.
