Linear Polarization
How else can we produce linearly polarized (LP) e-m waves?
- Absorp./reflect. of vector component of wave perp to “polarizer”
The E-field component parallel to the slots is absorbed and/or reflected.
The E-field component perpendicular to the slots is transmitted.
Long molecules absorb E-field parallel to molecule.
- Absorption produces LP e-m waves but in so doing it also reduces intensity of the wave. Question is: How much??
