Enhanced plane wave expansion analysis for the band structure of bulk modes in two-dimensional high-contrast solid–solid phononic crystals

•High contrast solid–solid phononic crystals were modeled using the plane wave expansion method that utilized the Inverse rule for obtaining the Fourier coefficients of the elastic tensor.•Utilizing the Inverse rule vs. the conventional Laurent's rule approach allows for the use of considerably...
