Description

A single pore is simulated, which may have thick walls. The top and bottom are curved cylindrically
azimuthally, and according to the Wolter I optic lengthwise (sagitally). A parameter specifies
whether this is hyperbolic or parabolic.
The azimuthal curvature is defined by the parameter radius. This refers to the center of the pore. I.e the top
and bottom plates have radius of curvature  and  respectively.

To intersect the Wolter I plates we take advatage of the azimuthal symmetry and only consider the radial component
of the photon's wavevector.

Input parameters

Parameters in boldface are required; the others are optional.
