A new scattering formulation for broad leaves

Scattering from thin dielectric objects is a classic research topic in electromagnetics. A traditional approach is to model thin dielectrics with resistive sheets, and for several canonical geometries of resistive sheet bodies. However, for many important geometries such as disks, exact solutions are not known and only approximate solutions can be applicable to limited cases of interest. In this paper a new approximate solution is formulated based on a volumetric integral equation using Fourier transform, and it is shown that the solution is uniformly valid from low to high frequencies at all incidence angles including edge-on incidence. Validity of the solution is demonstrated through a series of comparisons with known exact solutions and a numerical solution. Method of Moment, for canonical objects such as an infinite dielectric half-plane, strip, and a circular disk for 2-D and 3-D dielectric scatterers, respectively
