Academics

A microwave transmitter emits electromagnetic waves of a single wavelength. The maximum electric ?eld 1.36 km from the transmitter is 6.26 V/m. The speed of light is 2.99792 × 108 m/sand the permeability of free space is 4? ×10?7 N/A2.

(1) Assuming that the transmitter is a pointsource and neglecting waves re?ected from the Earth, calculate the maximum magnetic field at this distance.Answer in units of T

(2) Calculate the total power emitted by the transmitter.
