| Abstract(in English) | Reflection characteristics of wide frequency range electromagnetic wave absorber with wedge structure has been calculated by MMP (Multiple Multipole Program). Equivalent permittivity has been conventionally used to calculate a wedge structure. This method is low-frequency approximation. In this report, the wedge structure is analysed both by MMP and FD-TD methods. The result is compared with that of two kinds of equivalent permittivity approximation i.e. the transmission mode approximation and the uniform approximation. The reflection coefficient calculated by FD-TD shows good agreement with that of MMP with frequency up to 1.5GHz. And the coefficient calculated by equivalent permittivity differs from those of MMP or FD-TD in the higher frequency range. The applicable condition of transmission mode approximation and uniform approximation is considered. |
