Non-radiating sources in time-domain transmission-line theory

The concept of non-radiating sources is introduced to transmission lines in the time-domain analysis. A method is presented to construct localized voltage and current sources which do not produce any fields outside the source domain. These sources cannot therefore be detected by measurements made outside the source region. The importance of such sources for the uniqueness of the inverse source pro

Homogenization of a dielectric mixture with anisotropic spheres in anisotropic background

This paper treats the problem of calculating the macroscopic effective properties of dielectric mixtures where both the inclusions and the background medium can be anisotropic. For this homogenization process, the Maxwell Garnett -type approach is used where the inclusions are assumed to be spherical and embedded in a homogeneous background medium. The anisotropy of the background medium has to be
