Abstract

This article considers an electro-thermo-geometrical Multiphysics analysis of electromagnetic compatibility (EMC) resonance problem solution by using bandpass (BP) type negative group delay (NGD) equalization method. The rectangular cavity electric model based on EMC frequency domain S-parameter analysis is introduced. The unfamiliar BP-NGD function is specified in order to size the lumped electrical components of the suitable RLC-network based topology. The BP-NGD equalization principle is described including the Multiphysics synoptic analysis by means of electro- thermo-geometrical approach of the problem. The BP-NGD equalization methodology is proposed. The feasibility study of the EMC resonance equalization method is validated by considering a proof-of-concept constituted by 232.9×28×3.8 cm-size rectangular cavity. The BP-NGD active circuit is designed as equalizer by using RLC-series network. The EMC solution is verified by the BP-NGD POC specified by −4 ns NGD value at 0.644 MHz center frequency stating resonance effect reduction with 1-dB flatness. Furthermore, time-domain signal integrity (SI) analysis confirms the EMC cavity resonance resolution by showing output delay, over/under shoot reduction and also input-output cross correlation improvement from 89% to 99%.

电磁腔 BP-NGD 均衡的电几何灵敏度分析

本文探讨了利用带通（BP）型负群延迟（NGD）均衡方法解决电磁兼容（EMC）共振问题的电热几何多物理场分析。介绍了基于 EMC 频域 S 参数分析的矩形腔电气模型。为了确定合适的基于 RLC 网络拓扑结构的块状电气元件的尺寸，指定了陌生的 BP-NGD 函数。介绍了 BP-NGD 均衡原理，包括通过电热几何方法对问题进行多物理场同步分析。提出了 BP-NGD 均衡方法。通过对 232.9×28×3.8 厘米大小的矩形腔进行概念验证，验证了电磁兼容共振均衡方法的可行性研究。使用 RLC 串联网络设计了 BP-NGD 有源电路作为均衡器。在 0.644 MHz 中心频率下，BP-NGD POC 的 NGD 值为 -4 ns，说明共振效应降低，平整度为 1 dB，从而验证了 EMC 解决方案。此外，时域信号完整性（SI）分析通过显示输出延迟、过射/欠射减少以及输入输出交叉相关性从 89% 提高到 99%，证实了 EMC 谐振腔解决方案。
