A uniform electromagnetic plane wave in a lossless medium with ε = 9 and μ=μ has an electric field given by E(x,t) =ŷ sin(t+2лx)-32 cos(at+2x+6) (Note that y-component is expressed as a sin wave and the z component is negative) (a) Express the electric field in phasor form (use cosine reference!) (b) Determine the propagation direction and the polarization state of the wave in the following two cases. Find out the handedness in case of circular or elliptical polarizations. 1. δ= π/2 ii. 8=0 (c) Find the wavelength and the angular velocity w. (d) Calculate the intrinsic impedance of the medium and й(y) phasor for = 0. (e) Compute the time-average power density carried by the electromagnetic wave with 8=0.
