Abstract

In this paper a theoretical study on transmission phenomena of horizontally polarized shear waves propagating through a subwavelength solid probe surrounded by ridges is presented. In this context, the resonant components responsible for enhanced transmission and elastic beaming are identified as Fabry-Perot resonances inside the probe, and ridge induced Love waves. Apart from the fundamental interest, it is envisaged that the ability to enhance elastic vibrations through subwavelength channels and to focus the emerged field, will give rise to improved ultrasonic devices for sensing and testing applications.
