s- and p-polarizationsĀ
These animations show the s (or š)- and p (or š)-polarizations relative to a surface. When the electric field of an x-ray beam incident on a surface is (quasi-) perpendicular to the plane defined by the propagation direction and the surface normal, it is said to be š- or s-polarized (from the German for perpendicular, āsenkrechtā). When the electric field lies in the plane, the radiation is š- or p-polarized (from the German for parallel, āparallelā). The matlab code lets the user choose between the two.
