Research Abstract

Lightweight scattering component that can be applied for high-speed indoor wireless communications was proposed. Fundamental material composites were silicone rubber, metal and carbon nanotubes. In addition, precise propagation characteristic estimation method in WLAN office environments that consisted of multiple objects was developed based on large scaled numerical simulation. The validity of the chosen estimation method in large and complex multi-reflective environments was established by comparing calculation data obtained using this method with data obtained experimentally. Also in case of millimeter-wave RFID system development, these expertises can be applied.
