2-3. The electric field of a plane wave propagating in free space is given in complex nota- tion by E=10+20) Ux + 104 j(w+m/2+20mz) Uy Where U, and U, are unit vectors in the x and y directions of a right-hand coordinate system. a. In which direction is the wave propagating? b. Find the frequency of the propagating signal. c. Determine the type of wave polarization (linear, circular, or elliptical). d. Express the magnetic field intensity H of the propagating wave. e. Calculate the average power flow per square meter in the direction of the propaga- tion. I
