Abstract

This article proposes a class of single/multi-band waveguide protectors based on adaptive switching transmission poles (TPs) and transmission zeros (TZs). Switchable TPs and TZs are obtained by using multi-order transversal coupling schemes. Based on the incident EM wave with different frequencies and power levels, the frequency bands of the presented single/multi-band waveguide protectors are adaptively controlled. The power-dependent coupling scheme and coupling matrix synthesis provide guidelines for the proposals. For demonstration, single/multi-band waveguide protectors are joint-verified by physical modeling, full-wave simulation, EM/circuit co-simulation and low/high-power wave incidence experiments. The design example exhibits the merits of low insertion loss (IL) and high shielding effectiveness (SE). Also, the power threshold of −8 dBm and response time of 10 ns are proved.

基于自适应开关传输极点和零点的单/多波段波导保护器

本文提出了一类基于自适应开关传输极点（TPs）和传输零点（TZs）的单/多波段波导保护器。采用多阶横向耦合方式获得了可切换的TPs和TZs。根据入射电磁波的不同频率和功率水平，自适应控制单/多波段波导保护器的频段。功率相关耦合方案和耦合矩阵综合为该方案提供了指导。为了证明这一点，通过物理建模、全波仿真、电磁/电路联合仿真和低/高功率波入射实验对单/多波段波导保护器进行了联合验证。设计实例显示了低插入损耗和高屏蔽效能的优点。同时，验证了- 8 dBm的功率阈值和10 ns的响应时间。
