Antenna in a plane electromagnetic wave

AI Thread Summary
The discussion focuses on the behavior of a conducting wire placed in a plane electromagnetic wave propagating along the OX axis. The potential difference between the ends of the wire is expressed as E multiplied by L, where E represents the electric field strength and L is the length of the wire. It is clarified that the potential difference has the same frequency as the electromagnetic wave. The conversation emphasizes the relationship between the wire's orientation and the wave's propagation direction. Overall, the interaction of the wire with the electromagnetic wave is central to understanding its potential difference.

Consider please a conducting wire located in a plane electromagnetic wave propagating in the positive direction of the OX axis The wire is normal normal to the direction of propagation. Have you seen an expression for the potential difference between the ends of the wire?
Thanks in advance for your information.

thanks. i.e. it has the same frequency as the e.m/ wave has?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
