Impact of the tilted magnetic field on the propagation of oblique waves in the plasma superlattice

In its most general statement, we consider the problem of the impact of the external magnetic field on photonic properties of the superlattice comprising dielectric and conducting layers: the direction of the wave propagation as well as the direction of the external magnetic field are assumed to be arbitrary. We show that even a relatively weak external magnetic field can drastically alter the photonic spectrum of the superlattice, since within the photonic gaps there emerge photonic bands making the superlattice transparent for incident radiation. We demonstrate that the spectral width of photonic bands can be effectively controlled by rotation of the static external magnetic field. (C) 2020 Optical Society of America
