Abstract: In differential-form representation, the Maxwell equations are represented by simple differential relations between the electromagnetic two-forms and source three-forms while the electromagnetic medium is defined through a constitutive relation between the two-forms. The simplest of such relations expresses the electromagnetic two-forms as scalar multiples of one another. Because of its strange properties, the corresponding medium has been considered as nonphysical. In this study such a medium is interpreted in terms of the classical Gibbsian vectors as a bi-isotropic medium with infinite values for its four medium parameters. It is shown that the medium is a generalization of both PEC (perfect electric conductor) and PMC (perfect magnetic conductor) media, with similar properties. This is why the medium is labeled as PEMC (perfect electromagnetic conductor). Defining a certain class of duality transformations, PEMC medium can be transformed to PEC or PMC media. As an application, plane-wave reflection fr...

Scattering of Electromagnetic Radiation by a Perfect Electromagnetic Conductor Cylinder
TL;DR: An analytic theory for the electromagnetic scattering from a perfect electromagnetic conductor (PEMC) cylinder is developed in this article, which allows for the occurrence of cross-polarized fields in the scattered wave, a feature which does not exist in standard scattering theory.

Macroscopic quantum electrodynamics in nonlocal and nonreciprocal media
TL;DR: In this paper, the authors formulate macroscopic quantum electrodynamics in the most general linear, absorbing media and show that duality invariance only holds as a continuous symmetry when nonreciprocal responses are allowed for.

TL;DR: In this article, the Green dyadic was constructed in analytic form for a non-reciprocal anisotropic medium, and it was shown that when the medium is transformed to a bi-anisotropic one, its Green Dyadic can be obtained through the same transformation.
