Rotman Lens design with HFSS link

Two scripts for design of the Rotman lens and for the HFSS geometry file generation.

The design script generates a planar polygon with N vertices defined by coordinate vectors X and Y. Polygon represents the contour of the planar Rotman Lens (RL) based on the user-defined input parameters. RL port phase centers are obtained by the evaluation of the formulas published by Peter S. Simons, 2004.
The HFSS link script modifies the coordinates of the already existing HFSS file containing an arbitrary planar polygon with N vertices. A multi-line tool may be used to create such polygon. Input ASCII file consists of N coordinates represented by X and Y vectors defining the contour of the planar Rotman Lens (RL). To get input file run design script first.
