Reciprocity Method for Obtaining the Far Fields Generated by a Source Inside or Near a Microparticle

Abstract

We show that the far fields generated by a source inside or near a microparticle can be obtained readily by using the reciprocity theorem along with the internal or near fields generated by plane wave illumination. The method is useful for solving problems for which the scattered fields generated with plane wave illumination have already been obtained. We illustrate the method for the case of a homogeneous sphere, and then apply it to the problem of emission from a dipole inside a sphere near a plane interface.
