general properties of linear waves

Reflection coefficient Transmission coefficient X E H E H E H 0

What if? a Two perfectly conducting parallel sheets. Two plane waves. a

Parallel plates  = 0 implies no propagation in the z direction;  must be real for propagation x z a Two plane waves.

waveguide w E y is independent of y coordinate

Derive a dispersion relation for plane waves in a vacuum.
