Bending microwaves and forbidding frequencies with simulated metamaterials

Tuesday, April 7, 2020 - 09:10 in Physics & Chemistry

Using plasma to control microwaves for beaming direct energy toward a specific point is explored for their durability in high-energy electric fields and their reconfigurable structure. High power microwave beams, similar to lasers, can transmit energy at high speeds over long distances, unaffected by wind, gravity, or other forces. Aerospace engineers at the University of Illinois at Urbana-Champaign simulated a metamaterial formed from plasma structures to demonstrate its potential to tune microwave frequencies.
