The scattering and absorption of incident polarized radiation by thin flat circular disks composed of homogeneous isotropic material of complex refractive index is investigated by solving an integral equation for the induced currents. The method is particularly suitable for use in the resonant region where the free space wavelength is neither very small nor very large compared to the radius. Illustrative numerical results for bistatic, total, and absorption cross sections for broadside. and edge-on incidence are given, using refractive indices for ice in the ir.
