Abstract

This article proposes a combined dual-protection-mode energy-selective surface (ESS) for adaptive protection against high-power microwave (HPM) threats. By integrating protection modes of passband-shifted and passband-closed, the proposed ESS simultaneously realizes high in-band shielding effectiveness (SE) and ultra-wideband protection under HPM incidence. An equivalent circuit model (ECM) is established to reveal the two protection modes and their distinct yet complementary frequency regions. Based on this analysis, a three-layer ESS composed of diode-loaded periodic metallic structures is designed, enabling quasi-independent optimization of in-band SE and broadband shielding bandwidth. The experimental results show that the proposed ESS maintains a low insertion loss (IL) below 1 dB over a wide operating band under low-power microwave (LPM) incidence. Under HPM incidence, it achieves a broadband SE exceeding 10 dB over a fractional bandwidth (FBW) of 132.3%, and an in-band SE above 20 dB over an FBW of 30.5%. The work provides a general and scalable design framework for high-performance ESSs requiring simultaneous wideband and high protection capabilities.

一种具有宽带高屏蔽效能的组合双保护模式能量选择表面

本文提出了一种组合双保护模式能量选择表面（ESS），用于自适应保护高功率微波（HPM）威胁。通过集成通带移位和通带闭合两种保护模式，实现了高带内屏蔽效率和高pm入射下的超宽带保护。建立了等效电路模型（ECM），揭示了两种保护模式及其不同但互补的频率区域。在此基础上，设计了由二极管负载的周期金属结构组成的三层ESS，实现了带内SE和宽带屏蔽带宽的准独立优化。实验结果表明，在低功率微波（LPM）入射下，所提出的ESS在宽工作频带内保持了低于1 dB的低插入损耗（IL）。在HPM作用下，在分数带宽（FBW）范围内的宽带SE超过10db，达到132.3%；在FBW范围内的带内SE超过20db，达到30.5%。该工作为需要同时宽带和高保护能力的高性能ess提供了通用和可扩展的设计框架。

期刊介绍： The IEEE Transactions on Microwave Theory and Techniques focuses on that part of engineering and theory associated with microwave/millimeter-wave components, devices, circuits, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, and industrial, activities. Microwave theory and techniques relates to electromagnetic waves usually in the frequency region between a few MHz and a THz; other spectral regions and wave types are included within the scope of the Society whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
