Experimental studies of wave propagation in three-dimensional photonic crystals
… Selfcollimation of the propagating beam and ultrarefraction, where radiation is redirected through large angles in the crystal, are predicted. Although not considered as the ideal structure, the face centered cubic (fcc) opaline photonic is crystal studied for reasons of practical …
