MAXWELLS EQUATIONS FOR PHASORS
Propagation in z direction
GENERAL SOLUTION FOR PHASORS IN SPACE
Descartes coordinates
In general ELLIPTIC POLARIZATION
Special cases CIRCULAR or LINEAR POLARIZATION
GENERAL SOLUTION IN SPACE-TIME

LINEAR POLARIZATION
PHASOR VECTORS IN SPACE
GENERAL SOLUTION IN SPACE-TIME
Intrinsic (characteristic, or wave) impedance
Propagation constant

4.7 REFLECTION AND TRANSMISSION OF UNIFORM
PLANE WAVES
Transmitted wave
The wave is normally incident on a plane
interface separating two conductive media
Boundary conditions at
Reflected wave
