The typical quarter-wave constraint is replaced by the stipulation that a pair of adjacent layers should have a total optical thickness of one half of wavelength. Simple approximate analytic expressions are derived for the multiple bandgaps of the half-wave periodic structures.}, title={Multiple omnidirectional reflection bands from half-wave layered periodic structures}, type={artykuł}, keywords={optyka, thin films, multilayers, filters, bandgaps, 1D photonic crystals}, }
