FDTD法を用いた人体モデルによる電磁波散乱特性に関する数値的検討  [in Japanese] FDTD Numerical Examination of Electromagnetic Wave Scattering by a Human Body Model  [in Japanese]

A physical channel model for a static terminal used in indoors has been proposed. The proposed model can consider physical parameters such as moving people, their moving speed in order to evaluate various situations preciously, and an experimental verification is done. The model is two dimension, and assumes that a moving person is represented as a disk with diameter of Δw [m] and its moving person absorbs a part of the power of the paths across his width of Δw. In this article, we examine the scattering property by a human body which is modeled by the lossy dielectric cylinder using the FDTD method. Incident wave is assumed to be a Gaussian beam wave whose energy is concentrating on the propagation axis. The effect of the position of the cylinder and size of the spot size are examined.
