Evolution of exceptional points and anisotropic transmission resonance phenomenon for one-dimensional local resonant phononic crystal
In this study, a spring–mass physical model is proposed to study the complex band structure of a one-dimensional parity-time (PT)-symmetric local resonant phononic crystal. By solving the kinetic equations, the analytical solutions of the dispersion relation and effective mass are obtained. As is kn...
