Using PWE/FE Method to Calculate the Band Structures of the Semi-Infinite PCs: Periodic in x-y Plane and Finite in z-direction

This paper introduces the concept of semi-infinite phononic crystal (PC) on account of the infinite periodicity in x-y plane and finiteness in z-direction. The plane wave expansion and finite element methods are coupled and formulized to calculate the band structures of the proposed periodic elastic...
