Write the expression for the electric field intensity of a linearly polarized wave travelingalong the z-direction with E 0x = 2 V/m and E 0y = 1 V/m. Assume a phase shiftδ = 0 between the field components. Find the tilt angle ψ.2. (a) Write an expression for the electric field of a right-handed circularly polarizedwave with a frequency of 300 MHz and an amplitude of 2 V/m, traveling alongthe z-direction.(b) Assume that this wave is incident normally on a perfectly conducting wall, ofinfinite extent, located at z = 0. Determine the electric field intensity of the reflectedwave. Determine the polarization type and rotation sense of the reflectedwave.(c) Repeat (b) with the perfectly conducting wall replaced by a dielectric half-spacewith μ r = 1,ε r = 4. Write expressions for the reflected and transmitted wavesand determine their polarization as well as rotation sense.3. An elliptically polarized wave is traveling along the z-direction with E 0x = 2 V/m,E 0y = 3 V/m, and a phase shift δ =−30 ◦ between the field components. (a) Writethe expression for the electric field intensity and determine the rotation sense of thepolarization ellipse. (b) Determine the axial ratio, ellipticity angle, and tilt angle. (c)Calculate the polarization ratio P. (d) Determine the rectangular components of thefield in terms of the tilt and ellipticity angles using (13.20) and show that it agrees
