Abstract :
This report presents a design of wide angle and polarization insensitive circular ring metamaterial absorber working at 10 GHz. The structure is designed on lossy FR4 substrate sandwiched by thin copper layers. From the simulation, the circular ring metamaterial absorber can operates at wide incident angle, where they maintain high absorbance, which is more than 87% for incident angles as large as 70°. Due to the geometrical properties, this kind of absorbance is insensitive to any polarization state.
