Abstract
In this paper, a multiband symmetrical Jerusalem cross-shaped metasurface absorber is designed, fabricated, and measured. The upper layer consists of Jerusalem cross metasurface placed over FR-4 substrate to achieve perfect absorption. The unit cell of the proposed absorber is symmetrical and periodic in the horizontal and vertical axis. The Jerusalem cross absorber gives good impedance response at five different frequencies in the X-band region. The proposed absorber gives absorptivity of 97.3%, 97%, 96.1%, 98.8%, and 97.4% at 8.82 GHz, 9 GHz, 9.25 GHz, 9.43 GHz, and 10.1 GHz. In transverse electric and magnetic field response, the absorptivity is angle insensitive up to 600. The change in absorption spectra for the proposed absorber with a change in different physical parameters, electric field distribution is presented. The measured results of the fabricated absorber are similar to the numerically investigated results. The proposed absorber can be applicable in X-band satellite and radar applications.
