Abstract

The improved anomalous diffraction approximation for particle cross sections requires the induced polarization response to the incident electromagnetic field as an input. Solutions to Maxwell’s equations are developed for the induced polarization vector response for spheroidal particles. The emphasis is on near infrared wavelengths and micron sized particles. The model agrees with published results in the static limit. There is no published literature on the optical frequency dependence. General spheroidal shapes are examined. The goal is to apply the result to obtain the Muellar matrix.
