ON THE POSSIBILITY OF SUPPRESSING DIFFRACTION OSCILLATIONS NEAR THE PHOTONIC BAND GAP

摘要

Oblique light propagation through a chiral photonic crystal (PC) layer with gradient parameters of modulation is considered. The problem is solved by Ambartsumian’s layer addition modified method. It is shown that suppressing of diffraction oscillations near the photonic band gap (PBG) is possible at certain conditions. Thus, at certain conditions, the spectra for the finite PC layer is the same as that for the half space.
