This study reclassifies polarization elements using group theory, linking optical devices to mathematical concepts like boosts and rotations. It identifies new structures and degenerate elements within the Lorentz group framework.

Area of Science:

  • Optics and Photonics
  • Mathematical Physics
  • Group Theory Applications

Background:

  • Polarization elements are crucial for optical devices.
  • Existing classifications lack a unified theoretical framework.
  • Jones and Mueller matrices are standard representations.

Purpose of the Study:

  • To re-examine the classification of polarization elements.
  • To establish a group-theoretical connection for polarization elements.
  • To identify structures of homogeneous and degenerate elements.

Main Methods:

  • Group-theoretical analysis of polarization elements.
  • Mapping polarization elements to Lorentz group concepts (boosts, rotations).
  • Utilizing quaternion representation for homogeneous elements.
