Abstract
A new broadband electromagnetic absorber has been constructed by using the NiZn/NiZn ferrite hybrid structure and analysed using the FEM (finite eleme nt method). The structure is only 55.5 mm high, and has a reflection loss o f < -20dB in the frequency range 30 MHz-3GHz. These characteristics are sup erior to those of conventional absorbers which have been used in anechoic c hambers.
