Resonances in small scatterers with impedance boundary
Ari Sihvola, Dimitrios C. Tzarouchis, Pasi Ylä-Oijala +2
With analytical (generalized Mie scattering) and numerical (integral-equation-based) considerations we show the existence of strong resonances in the scattering response of small s…

Polarizability of Radially Inhomogeneous Subwavelength Spheres
Dimitrios C. Tzarouchis, Ari Sihvola
In this work the polarizability of a subwavelength core-shell sphere is considered, where the shell exhibits a radially inhomogeneous permittivity profile. A mathematical treatment…
