1. A plane wave in air is incident normally upon the surface of a lossless, nonmagneticdielectric medium with relative electrical permittivity of 25 at z=0. Incident E fieldhas an amplitude of 10 V/m polarized in +x direction and is of frequency 1 Ghz.Give the total E-field Phasor expression in air.2. For the problem (1), determine the average power density of the reflected wave,and that of the transmitted wave.3. Define and explain standing wave ratio. (Give a verbal description and theassociated expressions)4. For the problem (1), sketch the E-field wave pattern (Amplitude versus distancefrom the boundary) in air medium, indicating all critical vales and compute thestanding wave ratio in the medium.

Note : Out of given multiple questions, we solve only first question unless specified. You can…
