Beam tracing approach of 2×2 extended Jones matrix method for stratified uniaxial structures

In compliance with the commonly adopted small anisotropy approximation, a beam tracing modeling of a 2×2 extended Jones matrix algorithm is proposed, which traces the phase retardation along the geometric beam path, instead of along the normal direction, as the light beam is propagating through a stratified anisotropic structure. Consequently, polarization transformation at interfaces of the structure is unified by rotational operations of the coordinate system for light waves incident at both normal and oblique angles. Numerical simulations on optical transmittance demonstrate rational and consistent results with respect to currently prevailing algorithms.
