Unformatted text preview: (b) What is the dielectric constant of the medium? (c) describe the polarization of the wave. (d) ±ind the corresponding HFeld. 8. A 3 GHz, ypolarized uniform plane wave propagates in the + xdirection in a nonmagnetic medium having a dielectric constant 2.5 and a loss tangent 102 . (a) Determine the distance over which the amplitude of the propagating wave will be halved. (b) Determine the intrinsic impedance, the wavelength, the phase velocity, and the group velocity of the wave in the medium. (c) Assuming E = ˆy 50sin(6 π 10 9 t + π/ 3) V/m at x = 0, write the instantaneous expression for H for all t and x ....
