2.4 GHz helical antenna radiation pattern (NEC simulation) The Numerical Electromagnetics Code, or NEC, is a popular antenna modeling computer program for wire and surface antennas. It was originally written in FORTRAN during the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. The code was made publicly available for general use and has subsequently been dist
Electronics Research Group Instrumentation, Inference, and Applications Nec2++ The Numerical Electromagnetics Code (NEC-2) is a comprehensive package for the analysis of the electromagnetic properties of structures. It can analyse radiating properties i.e. antenna gain, as well as scattering properties (radar cross section) of structures. NEC-2 was originally written in FORTRAN. NEC2++ is an exten
