Summary form only given. The dielectric plate is an effective model for a vegetation leaf and thus an analysis of its scattering behavior is of fundamental importance. However, in configurations having arbitrary shape and composition, no effective high-frequency technique exists for their analysis. Existing numerical techniques are associated with matrix sizes of O(N**2) and are therefore inefficient and practically inapplicable for electrically large plates. The basis functions customarily used with these numerical techniques may pose a modeling difficulty when applied to plates of arbitrary shape. As an alternative to the traditional numerical methods, an iterative technique is considered for computing the current distribution caused by an incident wave (in any direction) on inhomogeneous plates of arbitrary perimeter.
