Conformal and polarization adjustable cloaking metasurface utilizing graphene with low radar cross section for terahertz applications

Metamaterials with precisely chosen negative permittivity and permeability are preferable to cloak the target without scattering. In this work, a metasurface is designed by using graphene as conducting material cylinder under instancing of TM TE polarized waves in terahertz range frequencies. The electric sheet impedance magnetic admittance played crucial role achieve cloaking good scattering reduction. Various incident angles simulated analyzed for obtaining radar cross section (RCS). proposed resonates at three different frequencies 3.8 THz, 9 THz 13.8 bandwidth resonating 3.5–4.58 THZ, 8.8–9.5 13–14.98 respectively. addition, parametric analysis chemical potential relaxation time shows effective results monostatic bistatic RCS simulated, which high reduction polarizations angles. structure adjustable various angle incidence less than 40 dB selected
