Abstract
A novel technique of generation of acoustic microwave is analyzed. The basic principle is similar to the distributed feedback concept used in lasers, where the oscillation feedback is provided by a periodic structure throughout the amplifying medium. A simplified model is analyzed in detail, and a number of configurations for oscillator device development are discussed.
