The high-speed electromagnetic analysis is achieved by using the ray-trace calculation with huge and small numbers of polygons that electromagnetically represent stable and mobile objects like constructions and vehicles, individually. The variable rays generated by the equivalent sources on the mobile objects and the fixed rays interacting with the stable objects obtain the EM field that is useful for the actual wireless communication. According to fewer number of variable parameters, the proposed cyber physical system than that of the conventional one drastically reduces time to calculate the EM field for the mobile wireless communication.本誌: 電気学会論文誌C（電子・情報・システム部門誌） Vol.144 No.12 （2024） 特集：電気・電子・情報関係学会東海支部連合大会本誌掲載ページ: 1172-1179 p原稿種別: 論文／日本語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejeiss/144/12/144_1172/_article/-char/ja/
