Hi eveyone, I am new to this forum and I hope that I can gain lots from this forum. Recently, one question comes into my mind, that is about the possibility of splitting the electric component and magnetic component of EM wave. This two components seem to always stick together. However, if they can be separated, I believe, EM wave can do more things than it does now. Can someone help me to analyse the possibility of splitting the EM wave into its component? Your help is truly appreciated ! Thank you !
