Updated: Mar 20, 2019

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
