초록
To construct an anechoic chamber for EMI test satisfying some international standards, it has been recognized that the absorption characteristics of the EM wave absorber must have more than 20 dB over the frequency band from 30 MHz to 18 GHz. In this paper, an EM wave absorber with super wide-band frequency characteristics was proposed and designed in order to satisfy the above requirements by using the EMCM[1]. As a result, the proposed absorber has absorption characteristics more than 20 dB over the frequency band from 30 MHz to more than 20 GHz.
