Abstract
Method based on application of a composite acoustic resonator for measurements of the absorption and velocity dispersion of high-frequency ultrasound waves is outlined. This method is realized in investigations of little absorption variations and phase velocity dispersion of sound in the ~ 140 mkm plate of iron borate (FeBO3) at a frequency of ~ 200 MHz.
