In this work,we propose a novel approach that combines a bidirectional deep neural network[BDNN]with a multifunctional metasurface absorber[MMA]for inverse design,which can effectively address the challenge of on-demand customization for absorbers.The inverse design of absorption peak frequencies can be achieved from 0.5 to 10 terahertz[THz],covering the quasi-entire THz band.Based on this,the BDNN is extended to broadband absorption,and the inverse design yields an MMA at the desired frequency.This work provides a broadly applicable approach to the custom design of multifunctional devices that can facilitate the evaluation and design of metasurfaces in electromagnetic absorption.
