Abstract

It is important for the design of wireless communication systems to clarify the characteristics of electromagnetic (EM) wave scattering from rain. This paper treats EM wave scattering from four perfectly conducting objects and numerically solves them by using the boundary element method. The objects have the shape of a sphere and an oblate raindrop and are on the top of a regular tetrahedron. Numerical results show that the amplitude of scattered wave is larger for raindrops than for spheres. As the distance between objects becomes longer, the amplitudes of forward and backward scattered waves vibrate. However, the center of vibration converges on a value.
