摘要

Many technical solutions in microwave acoustics are similar to these in optics. In this paper Bulk Acoustic Wave (BAW) microwave resonators and filters are discussed together with the devices that use the peculiarities of BAW propagation through semitransparent acoustic Bragg structures. An acoustic analogue of the resonator Fabri-Perott and acoustic resonant multilayered structures are considered. The use of a piezoelectric semiconductor resonant layer with electron drift provides the possibility of the amplification and generation of acoustic waves.
