Positive and negative extinction of active particles
Ari Sihvola, Henrik Wallén, Pasi Ylä-Oijala +1
Using analytical Lorenz--Mie scattering formalism and numerical methods, we analyze the response of active particles to electromagnetic waves. The particles are composed of homogen…
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…
Cloaking and Magnifying Using Radial Anisotropy
Henrik Kettunen, Henrik Wallén, Ari Sihvola
This paper studies the electrostatic responses of a polarly radially anisotropic cylinder and a spherically radially anisotropic sphere. For both geometries, the permittivity compo…
