Suppose you have a normal dipole antennae (transmitter and receiver) . Spin polarized current (as opposed to normal current) is sent into the transmitter, it emits an EM wave and the Receiver receives ...
I study the jellium model: conduction electrons free except for their mutual repulsion. We have the following vertex: ...
Is it true that the angular momentum of electromagnetic waves in an anisotropic medium is an integral of motion?
Extending my previous question Angular moment and EM wave, does it make sense to talk about the angular momentum of electromagnetic waves in an anisotropic medium? It is not obvious that the angular ...
