СТРУКТУРА АКУСТИЧЕСКОГО ПОЛЯ ИЗЛУЧЕНИЯ ФОКУСИРУЮЩИХ ПЬЕЗОПРЕОБРАЗОВАТЕЛЕЙ

Abstract

An acoustic field of radiation from focused acoustic transducers is calculated by the method of numerical analysis by using spherical piezoelectric plates and flat piezoelectric plates with lenses. It is shown that in the farzone the field has a non-uniform nature both on the axis of a piezoelectric plate and outside its axis.

Методом численного анализа рассчитано акустическое поле излучения фокусирующих акустиче-ских преобразователей на основе сферических пьезопластин и плоских пьезопластин с линзами. Показано, что в дальней зоне как на оси пьезопластины, так и вне оси поле носит неоднородный характер.
