Abstract

This letter presents the study of a reflection symmetric modal filter (MF) and meander lines (MLs) based on a four-layer printed-circuit board. The design goal is to experimentally investigate reflection symmetric MLs and MF to analyze their characteristics and to comparatively evaluate their effectiveness in protecting electronic equipment from ultrawideband (UWB) interference. The intuition behind this letter lies in leveraging modal distortions to decompose UWB pulses into smaller, less harmful components. A meander routing scheme is employed to increase the differences in mode per-unit-length delays, thereby improving interference attenuation while maintaining a compact design. The novelty of this letter includes the first experimental analysis of time responses for one-turn and two-turn MLs, providing significant insights into their behavior and performance. Experimental results, corroborated by electrodynamic simulations, demonstrate that MLs achieve superior attenuation of UWB pulses compared to MFs of equivalent size. Specifically, meander routing enhances UWB interference suppression of the initial MF by at least 2 times in ${N} _{1}$ , 1.63 times in ${N} _{2}$ , and 1.36 times in ${N} _{5}$ norms. In addition, a novel postprocessing technique is introduced to identify combinational pulses in the time response of the one-turn ML, advancing the understanding of pulse decomposition mechanisms. This method successfully demonstrated the presence of combinational pulses. This letter represents a notable advancement electromagnetic compatibility (EMC) by offering efficient and compact solutions for safeguarding electronic systems against UWB interference.
基于模态畸变的反射对称器件实验研究
本文介绍了一种基于四层印刷电路板的反射对称模态滤波器(MF)和弯曲线(MLs)的研究。设计目标是通过实验研究反射对称MLs和MF,分析它们的特性,并比较评估它们在保护电子设备免受超宽带干扰方面的有效性。这封信背后的直觉在于利用模态扭曲将超宽带脉冲分解成更小、更无害的分量。采用迂回路由方案增加了单位长度模式时延的差异,从而在保持紧凑设计的同时提高了干扰衰减。这封信的新颖之处包括首次对一圈和两圈ml的时间响应进行实验分析,为其行为和表现提供了重要的见解。电动力学模拟证实了实验结果,表明与同等尺寸的MFs相比,MLs具有更好的UWB脉冲衰减。具体来说,在${N} _{1}$规范中,弯曲路由对初始MF的UWB干扰抑制至少提高了2倍,在${N} _{2}$规范中提高了1.63倍,在${N} _{5}$规范中提高了1.36倍。此外,还引入了一种新的后处理技术来识别单转机器学习时间响应中的组合脉冲,提高了对脉冲分解机制的理解。该方法成功地证明了组合脉冲的存在。这封信通过提供有效和紧凑的解决方案来保护电子系统免受超宽带干扰,代表了电磁兼容性(EMC)的显著进步。
