- No Isolator Needed: Space-Time Metasurface Makes Light Reflect Only In One Direction
Light propagation usually goes both ways; it is reciprocal in that the trajectory of light traveling one direction is identical in the opposite direction. Isolators and circulators, which make light propagate only in one direction, are vital building block ...
