Antenna modelling

• The general field is called computational electromagnetics.
• NEC (Numerical Electromagnetics Code) is a very popular algorithm for modelling antenna performance.
  • it uses the "method of moments" to solve equations that are in boundary integral form (see more at computational electromagnetics)
• free software
  • NEC2.org — requires text files be created as input
  • 4nec2 — GUI
