Abstract :
A reconfigurable wideband metamaterial absorber based on lumped components is proposed. The wideband can be tuned with a -10 dB bandwidth of about 1.5 GHz by selecting certain values of the resistors and the inductors. The simulated results demonstrate that the designed absorber has good performance regarding polarisation insensitiveness and wide angles of incident waves for both TE and TM polarisations. The waveguide measurement method is used to verify the simulated result of the wideband metamaterial absorber.
