| Abstract: |
Polarimetric scattering is especially important in the understanding of physical phenomena. A scatterer near a waveguide (an engineered scattering element) can lead to a variety of evanescent field effects that significantly affect both the polarization and angular spectrum of the scattered light. Under direct imaging in a microscope, engineered scattering elements image as point sources where much of the rich physics is obscured. However, the pupil plane of a high-NA imaging system reveals important structure in the vector fields. In this work, we present a multipolar analysis of light scattered from engineered scattering elements using vector spherical harmonics as the basis set to illustrate how a scatterer can emulate an electric and/or magnetic dipole.
