Abstract

In this work, a wideband microwave resonating-type absorber is investigated in terms of metal backed metamaterial absorber (MMA). Expanded graphite-silicone (EG-Si) composite is encapsulated in the flexible silicone rubber matrix to build periodic unit cell of the MMA. Microwave material characterization of the EG-Si composites with different weight percentages (1, 3, 5, 7, 9 and 11 wt. %) is carried out at X-band frequency range. CST simulation is performed to optimize the unit cell parameters i.e. a wideband absorption with at least −10 dB absorption bandwidth (BW) throughout the X-band is obtained. Simulation is also carried out to check the polarization and incident angle dependency of the absorber’s absorption performance. The resonance and absorption mechanism of the absorber are investigated with the help of simulated electric field, magnetic field and current density inside the unit cell. The absorption of the prototype absorbers is experimentally measured by waveguide measurement technique.
