摘要

本文提出了一种由两个不同方形贴片阵列的电阻性元表层组成的超宽带(4 ~ 20 GHz)吸收器的优化设计。通过等效传输线电路模型，采用梯度下降和遗传算法对各参数进行优化。电路参数通过包含两个方形贴片结构的电阻元表面的多层来实现。设计了两种总厚度接近已知理论极限的吸波结构，并通过全波仿真对其性能进行了验证。

Optimal design of wideband radar absorbing structure consisting of resistive meta-surface layers

In this paper we propose an optimal design of ultrawideband (4 ~ 20 GHz) absorbers composed of two resistive meta-surface layers of different square patch arrays. Gradient Descent and Genetic Algorithm are employed to optimize all the parameters through equivalent transmission line circuit model. The circuit parameters are then implemented by a multilayer including two resistive meta-surface of square patch structures. Two types of such absorbing structures, with the total thicknesses close to that of the known theoretical limit, are designed and their performance are verified by full wave simulation.
