What happens when an object collides with a stationary wall at some incident angle? If this object is a ball, we often say that it "reflects" off the wall just like light does with the incident angle ...
Fabricated radio-wave absorber and measurement setup (a) at 30 GHz and (b) at 150 GHz. Measurement results at 30 GHz and (d) at 150 GHz. 5G wireless communication services have rapidly expanded ...
Despite of impressive successes already achieved on metasurfaces, most fascinating light-manipulation effects were only demonstrated under normal-incidence excitations. The angular dispersions of the ...
