Ellipsometry: What is it and Why is it Useful in Optics?
A propagating light beam is commonly known as propagating electromagnetic radiation within the field of physical optics. The direction of propagation is horizontal to the direction of the electric and magnetic field vectors, while the polarizing direction of light is understood to be the direction of the electrical vector component. As long as the route of the electrical field remains consistent throughout this propagation, light will be polarized directly. This illustrates that this electric field vector’s perpendicular components are in phase, or there is no instance of phase variation be...
