  1. NF2FF (Link): NF2FF is a planar near field to far field transformation for near field antenna measurement setups.

  2. rfMaxima (Link): rfMaxima is an RF toolbox for the wxMaxima computer algebra system. rfMaxima allows for symbolic derivation, as well as numerical evaluation (incl. Bode and Smith chart plotting), of 2-port network (ABCD, G, InverseABCD, H, S, Y, and Z), noise and stability parameters. Derivations are based on the solution of the set of Kirchoff current and voltage law equations representing the 2-port. Expressions can be exported to HTML or TeX. Figures can be exported to EPS or PNG.
