Evaluation of the Influence of Reflection from Wave Absorber to Body Area Measurement in Anechoic Chamber Using RMS Time Delay

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, several conditions such as absorber structures (planar and pyramid with various periodic lengths), transmitting positions relative to pyramid tip, receiving positions, and pair of transmitter-receiver polarizations are modeled by the finite-difference time-domain (FDTD) method to investigate the influence of reflections on body area channel measurements in anechoic chambers. The influence is evaluated by the error of root-mean-square (RMS) delay spread between the model with and without absorber. As from the investigation, the pyramid absorber with small periodic length outperforms the other structures. The body-normally polarized transmitter seems to be less influenced by reflections from absorbers.
