| Research Abstract |
In this study, the evaluation method of electromagnetic wave absorber panels and shielding materials are discussed. First, the diagonalization method of reflection coefficient matrix for absorber panels is proposed. By using this method, the reflection coefficients at principal axes and the directions of principal axes can be easily specified. Second, the measurement setup of reflection characteristic at millimeter waves is developed. The reflection coefficient of this setup can be correctly measured from 50GHz to 75GHz. Next, the transmission coefficient measurement setup of electromagnetic shielding materials at microwave frequencies is proposed. Transmission coefficients of several materials by this setup are discussed.
