# EMF Induced In A UHF Loop Antenna

A square loop of wire of a single turn, used as a UHF antenna, is located $$10^{5}$$ meters from an antenna broadcasting at a frequency of $$300 \text{ MHz}$$. The power of the source is 50 kilowatts. The loop of wire is oriented so that the magnetic component of the electromagnetic wave produced by the antenna is perpendicular to the plane of the loop and the wave number vector is parallel to two sides of the loop, and has side $$S$$ equal to the wavelength of the signal from the antenna.

What is the root mean square electromotive force $$(\text{emf})$$ generated in the loop?
