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. Nec2++ can analyse radiating as well as scattering properties of structures. The simulation engine in Nec2++ is compiled into a library for easy integration into automatic antenna design systems or GUI tools. Examples are included for using Nec2++ from C/C++, Ruby and Python.

Stars, PRs, issues and forks are under-captured in the later part of this window. GH Archive progressively stopped capturing non-push events during 2026 — −95% or worse by the end of the window. Every series here except Pushes fades for that reason, so a decline above reflects the archive, not this repository. Pushes stay reliable throughout, so read them, and the contributor counts derived from them, as the real signal. Data health has the measurements.
