A dual-polarized switchable microwave absorber

This paper describes a new design of dual-polarized circuit analog absorber, which is a two-dimensional periodic array of unit cells. Each unit cell consists of a top capacitive sheet, PIN diodes connected with microstrip lines on the middle layer, and a conducting ground plane. By changing the bias...
