DEFINITION

Classification: 333/195

With wave-modifying means (e.g., reflectors, resonators, diffractors, multistrip couplers, etc):

(under subclass 193) Subject matter including structure for modifying the amplitude, phase velocity, or propagation path of surface acoustic wave energy along the wave propagation path.

(1) Note. Included here are structures to establish surface acoustic wave resonance on selected portions of the propagation path.
