Abstract
This paper presents a thin wave absorber composed of mushroom structures. First, a dispersion diagram of the unit cell is shown. The thin wave absorber composed of mushroom structure can reduce RCS at two frequencies at oblique incident angles. The patch structures without via can also reduce RCS at lower frequency. The electric field distributions and the bistatic RCS pattern are shown.
