In this paper the acoustic transmission properties of multilayer structures was analyzed. Were compared binary and aperiodic (Severin, Thue-Morse) superlattices, Calculations were performed using the Transfer Matrix Method (TMM) algorithm. As a superlattice environment in the simulation the water was used. The material used to construct the structure was a PNM-0.38PT piezoelectric. Multilayer types have been selected so that the total number of layers for a given generation is equal in all structures.

In this chapter we introduce the basic characteristics of light modes in free space and in different kinds of optically confined structures including Bragg mirrors, planar microcavities, pillars and spheres. We describe the powerful transfer matrix method that allows for solution of Maxwell’s equations in multilayer structures. We discuss the polarisation of light and mention different ways it is modified including the Faraday and Kerr effects, optical birefringence, dichroism, and optical activity.

The water wave transmission properties and the frequency spectra of one-dimensional combination bottom of water and mercury with different filling fractions are studied by the transfer matrix method. For the periodic bottoms (PBs), the effect of the steps' numbers and the width on the band gaps are discussed. Each of whole band gaps is the juxtaposition of the gaps of three kinds of PBs, without covering. The numerical results show that the band gaps could be enlarged effectively by choosing the steps' width properly.
