Study and simulation of phononic crystal waveguides

Abstract

In the last 20 years, the emergence of (phononic crystals) has changed several concepts and opened several doors in various fields, and helped to present several applications that benefit humanity, and there are still many things that are still obscure and unknown until now, and some of them did not reach the point of experience and there are several Expectations in the near future. the purpose of this work is to create different structures of phononic crystals by applying different conditions using COMSOL, based on previous works on studying the behavior of the PC's, and trying to get new results that helps us to understand more the bandgap behavior and influencing in it, and produce waveguides to obtain high efficiencies in

transmitting information with high Q factor.

Key words: phononic crystals, waveguides, localized modes, COMSOL.
