Abstract
A slotted loop structured metasurface absorber has been designed with an independent angle of incidence and absorption useful for S and C band applications. The metasurface unit cell consists of square slots with an internally attached loop structure. The proposed absorber supports an insensitive angle of polarization. Metasurface absorber shows impedance matching at two resonating frequencies with the highest percentage of absorptivity. The proposed metasurface exhibits dual band characteristics which are at 3.2 and 7.6 GHz. For the transverse magnetic (TM) and transverse electric (TE) modes the absorptivity is obtained at 90 and 80% above values. The metasurface absorber is designed using a polyimide substrate having a thickness of 0.1 mm. The phenomenon of absorption is obtained in terms of E-field and surface current distribution patterns. Also, permittivity and permeability have been explained to analyze the metasurface’s properties. The metasurface absorber was prototyped and the results are measured for the simulated one and shows that both the results are in a good record.
