Is there any process or device that blocks EM waves of one phase (by any means, absorption, reflection, refraction, etc) but allows the transmission of EM waves of an alternate or opposite phase? Such that only waves of a certain phase can transmitted?
Alternatively, are there any devices/processed wherein the index of refraction is dependent on phase, such that waves of one phase will travel in one direction, and waves of an opposite phase will travel in a different direction (they will be refracted at different angles)?
