Question

424· The complex electric field of a uniform 4.26. In a source-free, free-space region, the plane wave is given by complex magnetic field of a time-harmonic field is represented by (a) Find the polarization of the wave (lin- ear, circular, or elliptical) (b) Determine the sense of rotation (clock wise or counterclockwise). (c) Sketch the figure the electric field where EO is a constant and Po is the intrin- sic impedance of free space. Determine the: (a) Polarization of the wave (linear, circu lar, or elliptical). Justify your answer (b) Sense of rotation, if any (c) Corresponding electric field. Show that any linearly polarized wave can be decomposed into two circularly polar ized waves (one CW and the other CCW) but both traveling in the same direction as the linearly polarized wave. traces as a function of ot 4.25.
