Waveguide Port Details Port must be large enough to cover the fields of the port mode of interest.

Waveguide Port Definition In addition to pick point, Full Plane or Free Coordinates can also be specifiedįor Separation of Degenerate Modes in Circular Waveguides Coaxial Pick Edge Also possible: any combination of pick points, edges, faces The wires attach the port to the structure Pick 2 points (or) 1 point and a face (or) enter coordinates (not recommended)ġ. Waveguide Ports deliver better match to the mode pattern as well as higher accuracy in S-Parameters.Discrete ports can be used for TEM-like modes, not for higher modes (fcutoff>0).Knowledge of TEM-Mode Line Impedance Voltage and CurrentĮ and H-Pattern, Line Impedance, nstant (beta+alpha) Picked faces, to be open after shelling 2. Picked faces are open after Shelling-Operationġ. Shell-Operation TASK: Waveguide-Bend, consisting of three shapes, should be shelled solid1 solid2Ĭombine to ONE shape 1. THREE Blend-Operations: Each edge blend aloneįor many edges, use SHIFT-E (picks closed edge chain) NOTE: Loft is even possible, if faces are not parallelīlend and Chamfer Edges ONE Blend-Operation: All 3 edges picked The new shape’s profile is morphed from the first picked face into the second. Loft-Operation Two picked faces, to be connected by new shape Double click corner points to move them around.Press BACKSPACE to delete previous picked point.The Local Coordinate System To align the WCS: pick face, edge or point, then: ShortCutĪlternative: use buttons Align WCS with picked pointĪdd sphere + brick Sphere (new shape) and Brick (old shape) Activate the tool (via Icon, Menu Objects->Pick or Shortcut) 2.
