摘要：

Analytical and experimental results are presented that demonstrate the advantages of replacing the metal mirror of a C-band transistor-grid oscillator with two types of selective-feedback mirrors. The first mirror is a two-dimensional photonic crystal, whose frequency-, polarization-, and reflectivity-dependent characteristics result in higher radiated power, lower cross polarization, and improved locking, The second is a diode-loaded grating functioning as an electronically tunable mirror, which allows the oscillator to be amplitude-modulated.
