Magnet/Piezo-free Metamaterial with Temporally Varying Elastic Properties
A metamaterial which allows acoustic waves to pass in one direction only.
Background:
Diodes allow electrical current to pass in one direction only which makes them fundamental to modern electronics. Unfortunately, an equivalent device does not exist for electromagnetic and acoustic waves. These waves are reciprocal, traveling equally well in...
