1. A plane wave in air has an amplitude of 6 V/m at (x, y, z) = (0, 0, 0), is z-polarized,and travels in the +y direction.(a) Find E and H.(b) Calculate the electric field phasor if the frequency is 3 GHz and y = 1.25 cm.(c) Find S and calculate the power density.2. For a ˆp-polarized plane wave E = ˆpE0e−jk·r, show that H = (ˆk × E)/η. Do this bytaking the curl of the given E.3. An electric field is E = ˆy 2ej120◦ e−j6x +ˆz 2 e30◦e−j6x. The medium is air. Find the(a) propagation direction(b) frequency-domain magnetic field(c) frequency(d) time-domain electric field(e) polarization.4. Find the polarization for a wave having(a) E = ˆx2e−jβz + ˆy2e−jβz(b) E = ˆxj2e−jβz + ˆy2e−jβz(c) E = ˆx2e−jβz + ˆyj5e−jβz(d) E = ˆx2e−jβz − ˆyj5e−jβz.5. A plane wave travels in Lucite and is incident on a dielectric–air interface. Theincident angle θi is measured from the surface normal. The relative permittivity is2.56, and the frequency is 3 GHz. Calculate the critical angle. For the perpendicularpolarization, calculate the propagation and attenuation constants β, α of thetransmitted field. Do this every 10o for θc≤ θi≤ 90o.Tabulate the results.
