Soft-and-Hard/D'B' Boundary Conditions and their Realization by Electromagnetic Media
I. V. Lindell, A. Sihvola
A layer of uniaxial medium with large axial permittivity and permeability can be used as a quarter-wave transformer with interesting properties. By increasing the transverse permit…

On Modeling Perfectly Conducting Sharp Corners With Magnetically Inert Dielectrics Of Extreme Complex Permittivities
Constantinos A. Valagiannopoulos, Ari Sihvola
The idea of replacing an edgy perfectly conducting boundary by the corresponding interface filled with a dielectric material of extreme complex permittivities, is examined in the p…

Realization of a spherical boundary by a layer of wave-guiding medium
I. V. Lindell, J. Markkanen, A. Sihvola +1
In this paper the concept of wave-guiding medium, previously introduced for planar structures, is defined for the spherically symmetric case. It is shown that a quarter-wavelength…
