Modelling a 2D diatomic lattice to visualize the elastic bandgap in sound-cancelling materials
Class: Electronic, Optical and Magnetic Properties of Materials (3.024)
Term: Spring 2018
This system models a sound-cancelling material as a two-dimensional diatomic lattice. Phonons are selectively blocked in the frequency range from 150—250 THz and >300 THz.
Modeled in Mathematica by Sara L. Wilson.
