Using a dynamic metasurface for amplification of free space radiation

Physicists have devised an ultra-thin dynamic amplifier for electromagnetic radiation using a parametric metasurface. A parametric metasurface is a thin composite material with small-scale surface structure, whose properties vary periodically over time, a recent advance beyond static or tunable metamaterials. The design enables significant control of freely propagating input radiation, including amplification of up to 10 decibels. Amplification...
