Dielectric media and polarization

  • School / Prep

    PREPA DES INP

Internal code

JP4POLAR

Description


Macroscopic aspects

Polarization vectors P and displacement vectors D.
Gauss's theorem for D. Passage relation between two media.
Potential and field created by a uniformly polarized medium.
Linear dielectric media. Dielectric susceptibility. Relative permittivity. Example of the dielectric plate capacitor.


Microscopic aspects

Polarisability: electronic, atomic, ionic, dipolar.
Local field (Lorentz).
Propagation of an electromagnetic wave in a dielectric:

Isotropic media (Drude-Lorentz model, variations in dielectric constant and refractive index, complex index)
Uniaxial anisotropic media (polarization plane and wave plane, neutral lines, action of a retarding plate on a given polarization, analysis of polarized light, interference in polarized light).
