Media with small permittivity, i.e., the epsilon-near-zero (ENZ) media, have drawn a great deal of attention from the fields of physics, materials science, and engineering. The wavelength in ENZ medium is in principle infinitely stretched, which induces spatially static while temporally oscillating wave dynamics.
