Abstract
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.
