Abstract
Transmission of surface acoustic waves through a delay line with periodic reflecting structures forming a Fabry-Perot resonator is studied. An expression for the wave transmission coefficient in such a structure is derived. It is demonstrated that a pair of strongly reflecting gratings can become completely transparent, i.e., the blooming effect takes place with the blooming area of an exponentially small width. The effect of temperature on the frequency response curve of a delay line with a Fabry-Perot resonator is experimentally investigated. The investigated effect is shown to be useful for fabrication of a bolometer detecting electromagnetic radiation.
