The Intensity variation of the Electromagnetic wave by Ring type Obstacles

환형 장애물로 인한 전자파 세기 변화

In mobile radio communication system involving geostationary satellites the field intensity of electromagnetic wave varies with frequency shape and location of an obstacle between a tramamitter and a receiver. In this paper a ring type obstacle between the propagation paths is presented. On the basis of Fresnel diffraction theory, the field intensity varying with ring-type obstacle’s radius is obtained by computer simulation.]
