angle insensitive metamaterial absorber has been presented in this manuscript.
The unit cell of the proposed design comprises of double square loop on the top
surface of a metal grounded dielectric substrate. The proposed design is
compact with its unit cell size of 9.5 mm, i.e., ??sub0/sub/4.4 and
ultrathin with the overall thickness of 0.038 ??sub0/sub corresponding to
the highest frequency of operation. The simulated results show dual absorption
peaks at 3.99 and 7.15 GHz with absorptivity of 65.94% and 88.65%,
respectively. The design is polarization and incident angle insensitive. The
structure shows more than 90% absorptivity at both the absorption frequencies
for the incidence angle of 60?°. A prototype of the proposed absorber design has
been fabricated and its performance has been experimentally verified for normal
and oblique incidences for TE and TM polarization. The measured results are
observed to be in agreement with the simulation response. The proposed design
is a potential candidate for
C band applications such as RCS reduction and electromagnetic compatibility
