Kerker Transform: Expanding Fields in a Discrete Basis of Directional Harmonics

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Parker R. Wray, Harry A. Atwater, , , | Summary: We present a linear coordinate transform to expand the solution of scattering and emission problems into a basis of forward and backward directional vector harmonics. The transform provides intuitive algebraic and geometric interpretations of systems with […]
