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.

期刊介绍： AEÜ is an international scientific journal which publishes both original works and invited tutorials. The journal''s scope covers all aspects of theory and design of circuits, systems and devices for electronics, signal processing, and communication, including: signal and system theory, digital signal processing network theory and circuit design information theory, communication theory and techniques, modulation, source and channel coding switching theory and techniques, communication protocols optical communications microwave theory and techniques, radar, sonar antennas, wave propagation AEÜ publishes full papers and letters with very short turn around time but a high standard review process. Review cycles are typically finished within twelve weeks by application of modern electronic communication facilities.
