UTD Ray Contributions
A number of optional ray contribution parameters are available when using faceted UTD to solve a face or faces.
Faceted UTD
- Direct field
- This option takes into account the direct rays.
- Edge and wedge diffraction
- This option takes into account the diffraction on edges and wedges.
- Surface reflection
- This option takes into account the rays reflected by the planar and curved surface.
- Creeping waves
- This option takes into account the creeping waves on curved surfaces.
UTD (Polygons and Cylinder)
- Direct and reflected
- This option takes into account both the direct rays and reflected rays.
- Double diffraction
- This option takes into account the double diffraction on edges and wedges and the combinations of reflections. Single diffraction rays are not included for this option.
- Edge and wedge diffractions
- This option takes into account the diffraction on edges and wedges. The ray may include an
arbitrary number of reflections, but only one diffraction. Note: The total number of interactions (number of reflections plus one) for the diffraction may not be larger than the value specified in the Maximum number of UTD ray interactions field.
- Creeping waves
- This option takes into account the creeping waves on a cylinder.
- Corner diffraction
- This option takes into account the corner diffraction.
- Cone tip diffraction
- This option takes into account the diffraction at the tip of the cone.
