The frequency-, polarization-, and reflectivity-dependent properties of photonic crystals are exploited to improve the performance of a grid oscillator. The metal reflector of a C-band grid is replaced with a photonic-crystal reflector, resulting in a higher cross-polarization ratio, higher radiated power, lower harmonic content, and improved start-up conditions.
