For the first time, the paper considers in a unified work the possibility of the appearance of additional pulses in various structures based on modal filtration technology, which is used to improve protection against ultrashort pulses (USP). We analyzed meander lines (ML) with broad-side coupling, structures with modal reservation (MR), reflection symmetric MLs, and modal filters (MF) with a passive conductor in the reference plane cutout and obtained the following results. It was found that the main reason for the additional pulses to appear in these structures is the introduction of asymmetry (of the cross-section, boundary conditions, and excitation). It is theoretically and experimentally established that additional pulses are a new resource for increasing the efficiency of protective devices with modal decomposition, but the highest effectiveness could be achieved through careful optimization.

从对称到不对称:基于模态过滤,使用附加脉冲提高对超短脉冲的保护

该论文首次在一项统一的工作中考虑了基于模态过滤技术在各种结构中出现附加脉冲的可能性,该技术用于提高对超短脉冲 (USP) 的保护。我们分析了具有宽边耦合的曲折线 (ML)、具有模态保留 (MR) 的结构、反射对称 ML 以及在参考平面切口中具有无源导体的模态滤波器 (MF),并获得了以下结果。发现在这些结构中出现额外脉冲的主要原因是引入了不对称性(横截面、边界条件和激发)。从理论上和实验上都证实,附加脉冲是一种新的资源,可以通过模态分解提高保护装置的效率,
