Low Frequency Scattering by Circular Dielectric Cylinder: New Polarizability Tensor

This paper considers the low-frequency scattering by a circular dielectric cylinder and modifies the exact polarizability tensor to extend the valid region of the known low-frequency solution. When compared to the traditional formulation, the proposed solution is shown to be valid for cylinders with a higher dielectric constant and larger radius. key words: low frequency scattering, polarizability tensor, circular cylinder
