摘要
常规的雷达吸波材料吸收来自入射到表面的电磁能量并将其转换为热能,本文介绍了一种新型的雷达吸波结构-相位转换平面,采用传输线理论分析了单层和多层相位转换平面结构的工作原理,并给出了不同类型的相位转换平面的频响特性,研究发现多层相位转换平面较单层相位转换平面在更宽的频带范围可以实现反射零点的动态控制,该型结构对于设计频率捷变的雷达吸波材料有重要的参考价值。
Conventional radar absorbing materials rely on the absorption and conversion the electromagnetlc energy incident upon them into heat. This paper introduces a new type radar absorb structure-phased switched plane, using the transmission theory to analyze the single-layer and multi-layer phased switched plane. Besides, frequency characteristic in different kinds of phased switched plane are given. The research result is that multi-layer phase switched plane can dynamically control the zero of the reflection over wider frequency domain, compared with single-layer phase switched plane. In addition, this structure is useful in designing the agile frequency RAM.
