(c) If the time averaged Poynting vector of the incident flux is 1 W·m-2 at 100 GHz, calculate the amplitude of the charge separation vector of the equivalent dipole. Evaluate the Thomson scattering cross-section, Ot, in the case of this radiation. (2 marks) (d) A small private plane approaching an airport is flying at an altitude of 2500 m above ground. The airport's flight control system transmits 100 W at 24 MHz, using a vertical dipole antenna. What is the intensity of the signal at the plane’s receiving antenna when the plane's position on a map is 4 km from the airport? (3 marks)
