Li. Deych et al., RESONANT-TUNNELING OF ELECTROMAGNETIC-WAVES THROUGH POLARITON GAPS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 57(6), 1998, pp. 7254-7258
We consider resonance tunneling of electromagnetic waves through an op
tical barrier formed by a stop band between lower and upper polariton
branches. We show that the tunneling through this kind of barrier is q
ualitatively different from tunneling through other optical barriers a
s well as from the quantum-mechanical tunneling through a rectangular
barrier. We find that the width of the resonance maximum of the transm
ission coefficient tends sharply to zero as the frequency approaches t
he lower boundary of the stop band. Resonance transmission peaks give
rise to new photonic bands inside the polariton stop band in a periodi
c array of the barriers.
