Imagine that the satellite described in the problem introduction is used to transmit television signals. you have a satellite tv reciever consisting of a circular dish of radius r which focuses the electromagnetic energy incident from the satellite onto a receiver which has a surface area of 5 cm2. how large does the radius r of the dish have to be to achieve an electric field vector amplitude of 0.1 mv/m at the receiver? for simplicity, assume that your house is located directly beneath the satellite (i. e. the situation you calculated in the first part), that the dish reflects all of the incident signal onto the receiver, and that there are no losses associated with the reception process. the dish has a curvature, but the radius r refers to the projection of the dish into the plane perpendicular to the direction of the incoming signal.
