To investigate general design methods, FDTD method is introduced for the analysis of matching characteristics of a ferrite absorber with multi-holes. The method of FDTD analysis is examined by comparing the theoretical data with the empirical one. Matching frequency characteristics are investigated particularly for the effect of a ferrite thickness by taking many kinds of parameter, such as a small hole size, an adjacent hole space, permeability, and permittivity into consideration. To change the matching frequency broadly using a single ferrite, it is found that the ferrite thickness plays important roll together with the small hole size, the adjacent hole space. It is clarified from general design charts that a thin absorber can be obtained, when the real and imaginary parts of permeability and real part of permittivity take large values.
