Abstract
In this paper, an optically transparent broadband microwave absorber is presented, which is polarization-insensitive as well as angularly stable. The proposed structure is made of indium tin oxide (ITO) based resistive sheets, which exhibits absorption bandwidth (above 90%) from 3.6 to 15 GHz, thereby covering C, X, and partial Ku bands. The absorption mechanism of the structure has been studied by analyzing several parametric variations. The proposed design has also been fabricated and experimentally verified under normal incidence.
