Abstract

The newly developed iterative extended boundary condition method (IEBCM) is extended to calculate the scattering by low-loss or lossless elongated dielectric objects. Specifically the iterative procedure is modified so as to utilize an initial assumption of the surface fields obtained from the Mie solution of a spherical object of the same dielectric properties. The solution for the elongated object is obtained by iteratively utilizing the regular EBCM technique to solve for objects of intermediate geometries between the substitute sphere and the object of interest. The other feature of the IEBCM which is related to subdividing the internal volume of the object into several overlapping subregions in each of which a separate field expansion is used is also utilized in the present extension. Results illustrating the adequacy of the IEBCM procedure to calculate the scattering by spheroids of an aspect ratio of more than 7:1 are presented.
