Abstract (in Japanese) (See Japanese page) 
(in English) Now recently, the number of customers who use cellular phones indoors is rapidly increasing. In this case, mobile terminals used in a stationary condition receives a level variation different from that in a moving condition. Then, it was proposed that a physical channel model for a static terminal used in indoors. 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 {${\Delta}$}w [m] and its moving person absorbs a part of the power of the paths across his width of {${\Delta}$}w.
In this paper, we verify the equivalent human bodydiameter of $\Delta$w from numeric viewpoint based on electromagnetic field theory as a human body to be loss dielectric cylinder.
