| Abstract(in English) | A Free Space Method is in wide spread use for the reflectivity measurement of electromagnetic wave absorbers, abbreviated as EMA, in VHF and UHF range. In a free space method, both the reflection levels from EMA and the metal plate of the same size are measured and the reflectivity is calculated by their ratio. The incident angle, such as normal, or oblique, must be specified, and the polarization of electromagnetic wave must also be specified as TE, TM, or circular-polarized mode. The working group of Japanese IEC/SC46F sub-technical committee is now working for constructing a standard of the twomethods, the one using the horn antennas and the other using antennas with dielectric lenses in order to measure the reflectivity of EMA in millimeter wave frequency range. In this paper, the method using only the horn antennas is studied experimentally. |
