Inverse design of microelectromechanically controlled scattering optical elements
TL;DR: In this article, a method of inverse design is applied to generate scattering optical element devices optimized for micromechanical control of the scattered light, and two designs are presented; the first design is a 1×2 switch with an expected crosstalk suppressed below -21 dB for both states.

Unitary analysis of T-matrix method in 2D dielectric scattering by TE wave incident
TL;DR: In this article, the full analysis of T-matrix structure is given, and when the boundary of a dielectric is limited to the cylindrical one, unitary transition from Tmatrix method to analytic solutions in two dimensional scattering is completed by TE wave incident.
