tmolteno/necpp

NEC2++ is a C++ rewrite of the Numerical Electromagnetics Code (NEC-2) with many new features like automatic error detection when you specify the structure incorrectly and much faster execution. The simulation engine in Nec2++ is compiled into a library for easy integration into automatic antenna design systems or GUI tools.
