A novel circuit analog absorber is presented in this letter, which consists of three layers: a complex impedance surface, a dielectric layer containing p-i-n diodes, and a conducting ground plane. The complex impedance surface is a periodic array of unit cells with lumped elements. p-i-n diodes are...
