McXtrace: ZonePlate

[ Identification | Description | Input parameters | Output parameters | Links ]

The ZonePlate Component

Zone plate based on Monte Carlo sampling of the Fresnel-Kirchhoff integral

Identification

  • Site:
  • Author: Erik Knudsen
  • Origin: DTU Physics
  • Date: June 16, 2009

Description

A component which models a zone plate by consierding the plate a secondary source
and then by means of Monte Carlo sampling, evaluating the Fresnel-Kirchhoff integral
implicitly by resampling the beam in a window defined by the focus_xw,focus_yh parameters.

Caveat emptor: this is a computationally heavy component to run.
The zone plate can be iether circular or linear. In the linear case, the "slits" are
along the x-axis.

Input parameters

Parameters in boldface are required; the others are optional.
NameUnitDescriptionDefault
radiusmThe outer radius of the zone plate. Triggers a circular zone plate. Takes precedence over xwidth,yheight.0
xwidthmWidth of linear zone plate.0
yheightmHeight of linear zone plate0
LmFocal length.
lambda0AAThe nominal wavelength that the zone plate is designed to focus.
focus_x0mOffset of resampling window along the x-axis.0
focus_y0mOffset of resampling window along the y-axis.0
focus_xwmWidth of the resampling window.
focus_yhmHeight of the resampling window.
distmDistance along the z-axis from zone plate to the resampling window.

Output parameters
