Photonic-Crystal Planar Antennas

E. R. Brown, C. D. Parker and E. Yablonovitch

Periodic dielectric structures have recently generated great interest because they can exhibit a forbidden range of frequencies, or photonic band gap, in the electromagnetic dispersion relation. In view of this property, these structures are called photonic crystals. They are well suited to electromagnetic-propagation and radiation-control applications, analogous to the current-transport and charge-control applications of semiconductors. An application that has recently been demonstrated at Lincoln Laboratory is the photonic-crystal planar antenna.
