Generalized solution of the paraxial equation
Tomasz Radozycki
A fairly general expression for a light beam is found as a solution of the paraxial Helmholtz equation. It is achieved by exploiting appropriately chosen complex variables which en…

Backflow in vector Gaussian beams
Tomasz Radożycki
The phenomenon of Poynting backflow in a single vector Gaussian beam is examined. The paraxial Maxwell equations and their exact solutions containing terms proportional to the smal…

Accurate paraxial Maxwell beams
Tomasz Radozycki
In this work, the paraxial version of Maxwell equations is derived with the use of two Riemann-Silberstein vectors. Exact solutions of these equations are then obtained representin…
