2. (20 points) The electric field for a TEM propagating wave in the time-domain is given as: E 15e cos(10π x 10° 2π Π 0.15-3) Find the following: a) Frequency of the wave in (Hz). b) Attenuation constant. c) Phase constant. d) Propagation constant. e) Wavelength of the wave. f) Phasor of the electric field. g) Phasor of magnetic field assuming intrinsic impedance of 300+j20 2. h) Complex Poynting vector and its direction. i) Direction of the propagation of the wave. j) Is the medium dispersive? Why?
