THE HATEROGENEITY ANALYSIS METHOD AND ALGORITHM IMPROVEMENT IN THE MEDIUM USING THE ACOUSTIC WAVE
Keywords:
ultrasound, heterogeneity, control, informational software, directed waves.Abstract
An acoustic method is developed, which allows to predict the distribution of an acoustic field in an environment with heterogeneity. Theoretical substantiation for calculation of acoustic wave parameters is presented. The approach of interaction of an acoustic wave with heterogeneity in the form of an ellipsoid is calculated by the finite element method in the software COMSOL. The results of the calculation are presented in the form of graphs.
