Plane Wave Expansion (PWE) for 2D (Fluid-Fluid) Sonic Crystals in MATLAB

Dataset

Description

The band structure of a two dimensional sonic crystal (fluid-fluid; longitudinal waves) is calculated in MATLAB using the Plane Wave Expansion method.

The bands, and any band gaps, are plotted using "makeDispFig_fluid_sqr_PWE.m" for square lattices, and "makeDispFig_fluid_hex_PWE.m" for hexagonal lattices.

Full details can be found in the text "A demonstration of a sonic crystal as an impedance matching layer to an ultrasonic piezoelectric transducer".
