Single Pore as part of the Silicon Pore Optics (SPO) as envisioned for the ATHENA+ space telescope.

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 <radius+pore_height/2> and <radius-pore_height/2> 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.
Example: MM_p( pore_th=0, ring_nr=1, Z0=12, pore_width=0.83e-3 , pore_height=0.605e-3, mirror_reflec=”mirror_coating_unity.txt”, R_d=0, size_file=”ref_design_breaks.txt”)
Parameters in boldface are required; the others are optional.
