The Mirror_parabolic Component
Idealized parabolic mirror

Description
Takes a reflectivity (default=1) as input and reflects rays in a ideal geometry parabolic mirror. The mirror is positioned in the zx-plane curving towards positive y. I.e. the focal point is (0,0,f(a,b)) The geometry of the paraboloid is governed by the equation: y = x^2 / a^2 + z^2 / b^2 Hence, the focal length for the 'x' curve is f=a^2 / 4, and analogous for z.
Input parameters
Parameters in boldface are required; the others are optional.| Name | Unit | Description | Default | |
| R | 1 | Reflectivity of mirror. | 1 | |
| a | sqrt(m) | Transverse curvature scale, if zero - the mirror is flat along x. | 1 | |
| b | sqrt(m) | Longitudinal curvature scale, if zero, flat along z. | 1 | |
| xwidth | m | Width of mirror. | 0.1 | |
| zdepth | m | Length of mirror. | 0.1 | |
| yheight | m | Thickness of mirror. If 0 (the default) the mirror is mathemticlly thin. Only has an effect for hitting the mirror from the side. | 0 |
| AT ( | , | , | ) RELATIVE | |||
|---|---|---|---|---|---|---|
| ROTATED ( | , | , | ) RELATIVE |
