The quasi-one-dimensional (quasi-1D) spoof surface plasmon polariton (SSPP) provides a new route for optically transparent electronic devices. The dispersion curves can control the electromagnetic wave propagation characteristics of the quasi-1D SSPP by manipulating the geometric parameters. However, the dispersion curves of quasi-1D SSPP have not been analytically derived and thoroughly studied. This paper derives the dispersion curves of the quasi-1D SSPP using equivalent permittivity and permeability methods, which can accurately predict the relationship between wave number and its geometric parameters. The simulation results validate the proposed dispersion curves. Based on the dispersion curves, this paper further presents a broadband optically transparent transmission line, which can achieve high-efficiency transmission from 3.0 to 14.4 GHz.

With the development of 5G communication and the continuous upgrading of AI algorithms, the realization of collaborative autonomous vehicles (CAVs) is gradually becoming possible. The perception layers of the current CAVs detect information mainly through simultaneous positioning and mapping (SLAM) and prior maps. However, SLAM requires exhaustive computing resources, and prior maps cannot cope with time-varying electromagnetic environments. Therefore, a complementary electromagnetic paradigm for CAVs is proposed, and a simple demo of this paradigm is created using commercial radio frequency identification (RFID) tags. Specifically, this paper takes vehicle localization as a specific application scenario in the absence of GNSS information, showing the great potential of applying this complementary electromagnetic paradigm to the decision layer of CAVs based on electromagnetic characteristic analysis. © 2022 IEEE.

Multi-domain characterization and a new fast detection method for acute illegal psychostimulants abuse detection based on waking-state EEG of mice is proposed in this paper. To get corftical electroencephalogram (EEG), three groups of mice were injected with cocaine (Coca), methamphetamine (Meth), and saline (Sali) respectively following the experimental paradigm of drug abuse. The EEG features were extracted out by multi-domain views, including time, frequency, complexity, dynamics, and independent domains to obtain acute drug abuse effects on the brain. New strategy combing time domain with frequency domain is developed as multi-domain input and by means of dimension transformation approach preserving temporal information, the performance of drug abuse detection is greatly improved with deep learning models of ResNet50. Results show that comparing to support vector machine (SVM), k nearest neighbor (kNN), random forest (RF), and long short-term memory fully convolutional networks (LSTM-FCN), Res-Net50 based on our proposed multi-domain features has best F1-score of 95.10%. This promising method provides a low-cost, fast, and widely assisted technology for psychostimulants abuse identification. © Published under licence by IOP Publishing Ltd.

This article introduces a comprehensive approach for designing and analyzing signal integrity in heterogeneous integrated systems that incorporate neuromorphic Darwin chips. The proposed integrated system architecture includes a neuromorphic Darwin chip, digital signal processing unit, microcontroller unit, field programmable gate arrays, and coding and decoding modules to encode and reconstruct analog spiking signals. The study evaluates the encoding module and the heterogeneous integration structure and conducts signal integrity analysis. To achieve optimal signal integrity performance, the article proposes a novel binocular eye diagram analysis technique. This innovative approach guides the encoding algorithm modification and improves the overall system performance. This research is the first to combine joint field-circuit simulation, heterogeneous integration modeling, and signal integrity analysis of the Darwin neuromorphic chip, and it is expected to serve as a valuable reference for future studies on similar systems. © 2022 IEEE.

This paper proposes a novel four-port calibration method for on-wafer S-parameter measurement. Crosstalk terms can seriously deteriorate the measurement accuracy of high-frequency on-wafer systems. The proposed method can consider all error and crosstalk terms in on-wafer measurement using two ground-signal-signal-ground (GSSG) probes and ensure high calibration accuracy. Only six calibration standards are required to complete the four-port calibration by this method. The proposed method is verified by full-wave simulations up to 100 GHz. The simulation and calibration results are in great agreement, which proves the correctness and reliability of the proposed method. © 2023 IEEE.

In this paper, a double-layer structured absorptive material for solving the electromagnetic radiation problems in chip-packages is proposed. This low-profile absorber structure is composed of two flat layers where the lower layer is made of absorbing material with high relative permittivity, while the upper layer is made of material with low relative permittivity to better meet the requirements of wide impedance matching. This structure is firstly designed based on theories and full-wave simulations. Then it is fabricated and applied to different absorbing materials working in the frequency range of 20-40GHz to suppress the radiation in a practical chip-package model. Finally, the effectiveness and universality of this structure are verified through measurements of the radiation suppression effect with different absorbing material settings. © 2022 IEEE.

A fast method for calculating the pattern of irregular MIMO antennas based on characteristic mode analysis and coupling matrix is presented in this paper. The radiation characteristics of each antenna are characterized by the characteristic mode analysis, and the interaction between antenna elements is characterized by the establishment of array coupling matrix. Unlike traditional simulation software that requires time-consuming re-modeling for each structural variation, our method only needs to modify the array coupling matrix to quickly solve the array antenna pattern. Two examples of irregular dipole antenna array and patch antenna array are used to verify the method, which demonstrate our method's ability to achieve high precision in significantly less time than conventional methods.

This paper presents a complete equivalent circuit model of a large memristor crossbar array, including parasitic capacitance, inductance, and resistance. By changing the rise time of the input signal and monitoring the output voltage of different output ports, signal integrity (SI) problems such as crosstalk, and IR voltage drop in the memristor crossbar array are analyzed. The simulation results show that with the decrease of the rise time, the electromagnetic effect will become obvious, which will lead to the crosstalk ripple and distortion of the output signal becoming serious. And as the output port moves away from the input, the IR voltage drop increases with the increase of the coupling elements. This will point the direction for improving the performance of memristor crossbar arrays. Furthermore, different from conventional signals, we propose to simulate spiking signals using the Izhikevich neuron model for more accurate analysis. © 2022 IEEE.
