To address the challenges of signal and power integrity in high-density interconnects, this paper presents a novel microwave analysis and intelligent optimization framework for high-speed link pin arrays design. A hybrid modal cascade (HMC) method incorporating the generalized T-matrix approach and the partial element equivalent circuit method is proposed to analyze the signal integrity of multi-layer structure with arbitrary shapes, which facilitates the rapid S-parameters calculation for trace-connected via arrays in advanced package. With the empirical formula of pin mutual inductance, a novel physics-assisted multi-objective genetic algorithm framework, designated as HMC-PMGA, is further introduced to optimize both pin arrangement and array parameters, ensuring compliance with both signal and power integrity requirements. Finally, results from various real-world high-speed link array configurations demonstrate the efficiency and reliability of the proposed algorithm, showing great potential for application in the electromagnetic integrity design of integrated circuits. © 2011-2012 IEEE.

A double-layer miniaturized metamaterial absorber based on the indium-tin-oxide (ITO) resistive film in a 5G millimeter-wave band is proposed in this paper. Its core structure is implemented by two layers. The first layer is a glass substrate with ITO resistive film attached, and another ITO is attached to the FR-4 substrate in the second layer. The simulation results reveal that under the conditions of transverse electric or transverse magnetic polarization, the absorption efficiency of the designed structure exceeds 90% in the bandwidth of 23.3GHz ~ 35.2GHz, and reaches the peak of nearly 100% at the resonant point of 28GHz. Further analysis shows that the absorption performance of the incident angle from 0° to 40° can reach more than 90% in the operating frequency, which is relatively stable.

International Applied Computational Electromagnetics Society Symposium (ACES)

作者： Xiaotian Yang Yan Li Erping Li Key Laboratory of Electromagnetic Wave Information Technology and Metrology of Zhejiang Province China Jiliang University Zhejiang China Key Laboratory of Advanced Micro-Nano Electronic Devices & Smart Systems and Applications Zhejiang University Zhejiang China

With the increase of the current operating frequency, the electromagnetic interference (EMI) problem of extra-highspeed electronic equipment and systems becomes more and more complex, and the traditional analysis and design methods cannot efficiently deal with the current EMI problems. Therefore, this paper proposes a method of predicting electromagnetic radiation using a two-dimensional (2-D) convolutional neural network (CNN) in deep learning. This method can quickly and accurately predict the maximum 3-m pin map (PINMAP) package radiation electric field. By comparing the prediction results with the full-wave simulation results, both results are in good agreement, and the CNN prediction time is at the millisecond level. Therefore, the method that can accurately and effectively predict the radiation value has been verified.

All-optical modulators with ultrahigh speed are in high demand due to the rapid development of optical interconnection and computation. However, due to weak photon–photon interaction, the advancement of all-optical modulators is consequently hampered by the large footprint and high power consumption. In this work, the enhanced sensitivity around an exceptional point(EP) from parity-time(PT) symmetry theory is initiatively introduced into a nonlinear all-optical modulator design. Further, a non-Hermitian all-optical modulator based on PT symmetry is proposed, which utilizes the large Kerr nonlinearity from indium tin oxide(ITO) in its epsilon-near-zero(ENZ) region. The whole system is expected to operate around EP, giving rise to the advantages of nanoscale integration and large modulation depth. This presented modulator with high efficiency and high-speed all-optical control can be commendably extended to the design methodology of various nanostructures and further prompt the development of all-optical signal processing.

In the current research field, metasurface technology has attracted much attention because of its excellent electromagnetic wave manipulation ability, and is widely used in the field of micro and nano photonics. In the lower frequency band, the megahertz band, metasurface technology also shows great potential for development, especially in the field of medical imaging, which is becoming increasingly important. However, the design process of metasurfaces is intricate and computationally costly. To tackle this challenge, this paper introduces a deep learning-based approach for the electromagnetic control and design of metasurfaces in the megahertz frequency band. By developing a Deep Neural Network (DNN), we are able to rapidly predict the electromagnetic response of metasurfaces, substantially reducing the time and memory consumption required for simulations. Moreover, the application of deep learning technology in metasurface design extends beyond forward prediction to inverse design, allowing for the prediction of metasurface structures that meet specific electromagnetic response requirements from the design objectives. This method overcomes the limitations of traditional design methods, offering new possibilities for the advancement of metasurface technology.

Electromagnetic interference (EMI) problems are common and can severely affect the normal function of high-voltage discharge circuits. This paper investigates the EMI issue in a dual-channel high-voltage discharge system, where the high-voltage discharging current of one circuit causes the false triggering of the other low-voltage triggering circuit. To effectively analyze the EMI coupling path, the near-field scanning (NFS) technique is adopted to capture and visualize the current flow path in the discharging process. A useful subtraction method is proposed to eliminate the radiated EMI from the high-voltage discharging current and better visualize the conducted EMI current. According to the NFS results after the subtraction process, the conducted EMI current coupling path can be straightforwardly obtained, and the corresponding mitigation approaches are demonstrated to solve the EMI problem effectively.
