Abstract (in Japanese) (See Japanese page) 
(in English) Nowadays, in next generation mobile communication systems (6G), the use of RIS (Reconfigurable intelligent surface), which enable active control of reflection direction of radio waves, has been investigated in order to prevent coverage hole and improve communication quality in high frequency bands. Here, conventionally, the propagation characteristics of the reflected waves by RIS have been evaluated by the bistatic RCS pattern of RIS and the radar equation. However, this method deteriorates accuracy and efficiency in the evaluation of the vicinity of RIS and the multipath environment. To solve these problems, this paper propose RIS scattering model based on physical optics. In addition, the results of evaluating the effect of installing RIS in an indoor L-shaped corridor using this model are shown.
