Scattering Properties of Spherical Time-Varying Conductive Shells
arXiv:2105.00058 · doi:10.1109/TAP.2022.3177423
Abstract
Harmonic generation in the scattered fields produced by a dielectric sphere coated with a time-varying conductive shell is studied using a Mie theory approach hybridized with conversion matrix methods. Analytic results are derived for plane wave incidence as well as in a more general transition matrix setting. An equivalent transmission line approach is also discussed. Numerical examples validate the derived expressions through comparison with purely numerical methods and convergence characteristics are explored. Several additional examples illustrate unique trends in far- and near-field scattering.
