Synthetic composite structures, known as metamaterials, have been increasingly applied in
the past two decades in numerous applications for obtaining electromagnetic characteristics far beyond
naturally occurring materials. In particular, epsilon-near-zero (ENZ) media are a special category of
metamaterials which have been shown to exhibit exotic wave-matter interaction properties, rendering
them suitable for numerous applications. Exploiting the distinctive property of spatial uniformity of the
magnetic field in 2D ENZ (i.e. infinitely extended along a given direction) media, it has been recently
theoretically and experimentally demonstrated that a 2D ENZ body doped with a dielectric inclusion is
equivalent to a magnetic ENZ medium for an outside observer, a concept coined “photonic doping”. In
this dissertation, I theoretically extend this concept for additional classes of inclusions and propose
several potential applications harnessing the peculiar electromagnetic characteristics of such structures.
