Abstract

This paper studies the transmission of elastic waves into test specimens for cylindrical waveguide based ultrasonic transducers. However, in order to achieve better mode focusing, topographical waveguides with conical profile were studied. Finite element simulations were used to study wave propagation and transmission into specimen samples using such ‘transmission horns’. Fundamental Longitudinal mode L(0,1) was generated in cylindrical rods. Results show that a 50° conical transition profile help achieve better transmission and beam directionality into the specimen and also better reception of the back wall reflections at the waveguide as compared to a simple cylindrical rod waveguide.
