Antenna in a plane electromagnetic wave

Click For Summary
SUMMARY

The discussion focuses on the potential difference generated across a conducting wire placed perpendicular to a plane electromagnetic (e.m.) wave propagating along the OX axis. The key expression derived is that the potential difference (V) is equal to the product of the electric field strength (E) and the length of the wire (L), expressed as V = E × L. Additionally, it is confirmed that the frequency of the potential difference matches that of the incident e.m. wave.

PREREQUISITES
  • Understanding of electromagnetic wave propagation

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.

The pot difference is E X L.
 
e.m. wave antenna

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