  1. Through the Looking Glass and What We Found There E B k Reduced phase velocity: n Absorption: k

  2. TM TE Brewster’s Angle At Brewster’s Angle, the Transverse Magnetic mode is not reflected, leaving only a Transverse Electric polarized reflection.

  3. TE + TM TE “glare”

  4. Physical Interpretation An oscillating charge radiates strongest perpendicular to the oscillation, and zero along the oscillation. At Brewster’s angle, the refracted beam causes dipoles to oscillate along the reflected direction.

  5. Homogeneous - same properties at all points. opposite: inhomogeneous Isotropic - same properties in all directions. opposite: anisotropic Polarizers, phase retarders, and rotators: based on anisotropy in n+jk

  6. Linear Polarizer “dichroism” • The effect of causing white light to be split into colors. 2. • The effect of causing different polarizations to be absorbed by different amounts (anisotropy in k).

  7. analyzer polarizer transmission axis (TA) TA vertical TA horizontal Linear Polarizer The effect of a polarizing element is described by its Jones Matrix, which multiplies the light’s Jones Vector. TA at q
