Problem 2

The electric field of a plane wave propagating in a medium is given by

E = [ŷ3 sin( × 107 -0.2x) + 24 cos( × 10² -0.2лx)] (V/m)

1. Find the propagation velocity of the field.

2. The medium has permeability o. Find its relative permittivity €.

3. Is the wave a plane wave?

4. Use both time-domain and phasor-domain Maxwell's equations to find the

magnetic field H.

5. Determine the average power density carried by the wave.
