Finite element analysis of surface elastic waveguide based on pyramidal phononic crystal
Abstract In this paper, a pyramidal phononic crystal waveguide, deposited on a thick substrate made of silicon, is studied. The pillars are arranged in a square array on the top surface of the substrate. By using the finite element method, the surface modes are investigated, and the band structures...
