Consider a satellite in stationary orbit that beams a signal earthward with a power of 4.9 kilowatts and a beamwidth covering a circular region with diameter 193 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 ln = 1.257×10-6 H/m and the free space permittivity e, = 8.85x10-12 F/m.
