Abstract

In this paper, a miniaturized, self-actuated, energy selective spatial filter is designed for achieving field intensity dependent electromagnetic (EM) protection in a working frequency band. The spatial filter is periodic with each unit loaded with four microwave nonlinear devices. The dimension of the unit is in size of λ/16 and is ultrathin. Structural design, mechanism of operation are presented and discussed. A full-wave simulation is carried out for obtaining the transmission characteristic of the spatial filter. Results show that the received field intensity by using the spatial filter can be well controlled with a variable power loss from 0.1 dB up to 24 dB, and the spatial filter has a stable transmission characteristic to different incident angles. Therefore, the spatial filter is able to distinguish small signals from strong incident waves and can be utilized in EM protection against high power microwaves.

一种小型化、自驱动、能量选择的空间滤波器

本文设计了一种小型化、自驱动、能量选择的空间滤波器，用于在工作频段内实现场强相关的电磁保护。空间滤波器是周期性的，每个单元加载四个微波非线性器件。该装置的尺寸为λ/16，超薄。介绍了其结构设计和工作机理。为了获得空间滤波器的传输特性，进行了全波仿真。结果表明，该空间滤波器可以很好地控制接收场强，功率损耗在0.1 ~ 24 dB范围内变化，并且在不同入射角下具有稳定的传输特性。因此，空间滤波器能够从强入射波中区分小信号，并可用于高功率微波的电磁防护。
