Stokes Parameter Formalism is a mathematical framework used to describe the polarization state of electromagnetic waves, especially in optics and astrophysics. It was developed by George Gabriel Stokes, an Irish mathematician and physicist, in the 19th century.

The Stokes parameters, denoted by I, Q, U, and V, are used to describe the state of polarization of electromagnetic waves. These parameters are derived from the coefficients of the power term, the linear term, the circular term, and the linear term, respectively, in the Taylor series expansion of the wave's electric field. The Stokes parameters are a measure of the amount of polarization present in a wave, as well as the orientation of the polarization state.

The Stokes parameter formalism has important applications in optics, including the analysis of polarized light from astronomical objects, the measurement of optical properties of materials, and the study of nonlinear optical phenomena. In astrophysics, it is used to study the polarization of light from stars, galaxies, and other celestial objects, which can provide valuable information about the magnetic fields, dust content, and other properties of these objects.

The Stokes parameter formalism has undergone significant development and refinement since its introduction, with the inclusion of new parameters and the development of new methods for calculating the Stokes parameters. It remains a fundamental tool in the study of polarized light and is widely used in various fields, including optics, astrophysics, and applied physics.
