A satellite in stationary orbit that beams a signal earthward with a power of 10 kilowatts and a beamwidth covering a circular region with diameter 67.5 km on Earth. What is the root-mean-square electric field strength at the receiver within the illuminated area, assuming a uniform energy distribution? Use the free space permeability μ0 = 1.257×10−6 H/m and the free space permittivity ϵ0 = 8.85×10−12 F/m.
