DeWitt-Schwinger Renormalization of in Dimensions
Robert T. Thompson, José P. S. Lemos
A compact expression for the DeWitt-Schwinger renormalization terms suitable for use in even-dimensional space-times is derived. This formula should be useful for calculations of $…
Transformation Optics in Nonvacuum Initial Dielectric Media
Robert T. Thompson
Previous formulations of transformation optics have generally been restricted to transformations from relatively simple initial media, such as the vacuum, because of limitations du…
Dielectric Analog Space-Times
Robert T. Thompson, Jörg Frauendiener
We generalize the notion of a dielectric analog Schwarzschild black hole model to analog models of arbitrary space-times; in particular, the approach is not restricted to static sp…
Generalized Transformation Optics of Linear Materials
Robert T. Thompson, Steven A. Cummer, Jörg Frauendiener
We continue the development of a manifestly 4-dimensional, completely covariant, approach to transformation optics in linear dielectric materials begun in a previous paper. This ap…
A Completely Covariant Approach to Transformation Optics
Robert T. Thompson, Steven A. Cummer, Jörg Frauendiener
We show that the Plebanski based approach to transformation optics overlooks some subtleties in the electrodynamics of moving dielectrics that restricts its applicability to a cert…
