Electromagnetic Waves Scattered by Conductor Plane on the Earth

Abstract

An open site is a place measuring electromagnetic waves emitted by electronic apparatuses, and it is estimated as a field over an infinite conductor plane on the earth. However, for a measuring field in practice, a finite conductor plane is laid on the earth. In this paper, we considered the influence of a finite ground plane and the peripheral earth. The numerical calculation was performed for a finite plane on the earth and in free space (a strip), and for an infinite plane. As a result, the fields diffracted by edges of a finite plane on the earth are small compared with the strip.
