Hi all! I was thinking if it is possible to revert the Faraday effect. If I have a magnetic field, it interacts with EM wave (light) by changing its polarisation. Can I got a variable magnetic field interacting with polarised light so that I can get induced current in a coil? I can understand it is something similar to Nantenna, and I can understand that I need nano coils which are difficult to realize but I was thinking more to utilize special materials as mean (or crystals) to be at the right wave lenght to get induced current in a coil. Is there any research in this? any link to suggest to me?
