  • In this Paper, a super wide-band EM wave absorber was designed by attaching pyramidal type absorber on a ferrite absorber. The used ferrite absorber was in hemisphere type on a cutting cone-shaped absorber. As a result, the bandwidth has been broadened from 30 MHz to 18 GHz and the total height of the EM Wave absorber is relatively low profile of 14.26 cm.
