***CMS-9730779BogyNumerically efficient and mathematically rigorous tools are developed for theoretical study of problems of wave propagation in composite wedges. Experimental and theoretical studies are conducted for the scattering of surface acoustic waves by a solid wedge adhered to a solid half-space made from another material. These developments have a broad variety of technical applications in seismology, geophysics, acoustoelectronics, ocean acoustics, nondestructive ultrasonic evaluation, radar, and mobile telecommunication systems.***

*** cms - 9730779bogys开发了数值高效和数学严谨的工具，用于复合楔形波传播问题的理论研究。本文从实验和理论两方面研究了表面声波在固体楔块与由另一种材料制成的固体半空间之间的散射。这些发展在地震学、地球物理学、声电子学、海洋声学、无损超声评估、雷达和移动通信系统等领域有着广泛的技术应用
