地下街およびビルの廊下内電波伝搬
詳細
This paper is concerned with the electromagnetic field estimation in underground passage and building's lobby. They are assumed to be composed of concrete walls and their floor and ceiling are flat and parallel. However, their structure may be complicated with junctions as well as bends. First we describe about the ray searching algorithm based on the image method. Second we show some rays in underground and building in two-dimensional and three-dimensional ways. Finally we show an example of field distribution in a building.
