1. a) In a certain media the electric field is given by E = 10 Cos(10°t – 3y) £ V/m. What type of medium is it? (i.e., is it free space, a lossy dielectric, a lossless dielectric, or a good conductor?) Explain. b) An AM broadcasting station operates at 1 MHz. If you are 1 km away from the station are you in the near field or the far field? Explain. c) What is the effective area of an antenna? d) It was shown under load matched conditions that only half of the power received by an antenna is dissipated in the load. What happens to the other half of the power? e) Explain how electronic bean steering is accomplished. 1. a) In a certain media the electric field is given by E = 10 Cos(10°t – 3y) £ V/m.
