Prоblem C.1 (10 pоints) A unifоrm plаne wаve of frequency 1 GHz trаvels in air and is incident normally on a lossless non-magnetic with dielectric constant of 9 (see figure). The E field of the wave has a peak amplitude of 5 (V/m) and an initial phase shift of 45o. Find the following: (a) Expression for the incident electric field vector in the time domain (3 points) (b) Expression for the transmitted magnetic field intensity in the phasor domain (3 points) (c) Expression for the reflected electric field intensity vector in the time domain (3 points) (d) Orientation of the reflected magnetic field intensity vector (1 point) Problem C.2 (5 points) (a) For a radar operating at 50 GHz, a radome is made of material with dielectric constant 2.1 (see figure). Determine the minimum possible values for thickness of the radome, s and distance from the antenna, d (2 points). (b) An electromagnetic wave with parallel polarization travels through air and illuminates a non-magnetic material with dielectric constant of 16. Sketch of the variation of the magnitude of the reflection coefficient at the boundary between the two materials as a function of angle. Calculate the magnitude of reflection coefficient at normal incidence. Label important features on the graph (3 points)
