Design of ultrawideband photonic crystals for broadband antenna applications

Face-centred-cubic photonic crystals with overlapping stop bands are stacked in tandem to obtain an ultrawideband photonic crystal. This crystal has a stop band that extends from 16 to at least 25 GHz and has a minimum rejection of ~7 dB at normal incidence. Different stacking configurations have been studied, and cavity modes between nonadjacent crystals with overlapping stop bands have been observed
