UTD Ray Contributions
A number of optional ray contribution parameters are available when using the uniform theory of diffraction (UTD) to solve a face or faces.
On the Solve/Run tab, in the
Solution settings group, click the Solver settings icon.
On the Solver settings dialog, click the High
frequency tab.
- Direct and reflected
- This option takes into account both the direct rays and reflected rays.
- 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.
- Corner diffraction
- This option takes into account the corner diffraction.
- 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.
- Creeping waves
- This option takes into account the creeping waves on curved surfaces.
- Cone tip diffraction
- This option takes into account the tip diffraction at the tip of the cone.
