Abstract
A Minkowskian isotropic medium (MIM) is a special kind of a Tellegen medium, i.e, a nonreciprocal and achiral bi-isotropic medium. The MIM is defined, in 4D representation, as a truly isotropic medium, i.e, it is isotropic for any inertial observer. The perfect electromagnetic conductor (PEMC) was defined by Lindell & Sihvola and generalizes two known media: the perfect electric conductor (PEC) and the perfect magnetic conductor (PMC). The PEMC was proposed in the literature as a new type of boundary. Nevertheless, it can be regarded as a real medium for electromagnetics corresponding to a specific limit of a MIM. Our main goal is to study, using the standard transmission line framework, the electromagnetic wave propagation in a waveguide with a MIM cladding. The special case where the MIM cladding is reduced to the PEMC cladding is highlighted. The nontrivial electromagnetic field profile inside the PEMC can only be calculated by regarding this medium as a particular case of a MIM.
