Question: The configuration shown in the figure depicts two vertically oriented half-wave dipole antennas pointed towards each other, with both positioned on 100- m-tall towers separated

The configuration shown in the figure depicts two vertically oriented half-wave dipole antennas pointed towards each other, with both positioned on 100- m-tall towers separated by a distance of 5 km. If the transit antenna is driven by a 50-MHz current with amplitude I0 = 2 A, determine:
(a) The power received by the receive antenna in the absence of the surface. (Assume both antennas to be lossless.)
(b) The power received by the receive antenna after incorporating reflection by the ground surface, assuming the surface to be flat and to have r =9 and conductivity 0€“3 (S/m).
