Abstract

The present paper is the first of a series of papers dealing with studies of the electromagnetic field over geometrically complex models. Thin sheet modelling was used to describe the behaviour of the EM field in 3-D situations, and investigate the behaviour of parameters used in EM studies. In this paper, the morphological characteristics of the five electromagnetic field components over structures of complex geometry are studied. The five electromagnetic field components are mapped over three models having different geometrical complexity, and the main features of the behaviour of each component are outlined. The results of the numerical computations also show that the morphology of normalized quantities can be approximated by that of the combination of the electric components. -from Authors
