Abstract
In recent years, the mobile Internet has been increasing. The mobile radio communication tools used indoors are the cellular phones, PHS, IMT-2000, the wireless LAN, Bluetooth, and so on. They are used at sub-micro wave band(1-3GHz). Since the electromagnetic interferences between mobile communication systems have become the problem the necessity for the thin sub-micro wave absorber suited for interior decoration is increasing. In this paper, we focus on the ferrite wave absorber of wedge structure and analyze its reflection characteristics depended on structure by FDTD method. As the result, we can obtain the wedge ferrite wave absorber, which has the reflection coefficient of less than -20 dB at sub-micro wave band.
