Photonic crystals as host material for a new generation of microwave components

[摘要] In order to verify simulations of a concave lens based upon a photoniccrystal, it was scaled and built for the application in the microwave range.Its field distribution was measured between 5.5 and 12 GHz. Due to theeffective refractive index smaller than 1, focusing points were found inspite of the concave shape. The survey of the field distributions at theinvestigated frequencies leads to other possible applications of photoniccrystals in the microwave and millimetre wave region, like beam-splitter andprism.
