What is Numerical Electromagnetics Code (NEC)?
The Numerical Electromagnetics Code (NEC) is an outgrowth of a program developed in the 1970s, called the Antenna Modeling Program (AMP). There are at least 4 versions of NEC, with NEC-2 emerging in 1981 and NEC-4 appearing in 1992. NEC-2 is the highest version of the code under public domain. NEC-4 remains proprietary with the Lawrence Livermore National Laboratory and the University of California. It requires a separate license for use.
NEC in all its forms is a computer code for the analysis of the electromagnetic response of antennas and other metal structures that uses method-of-moments techniques for the numerical solution to integral equations for the currents induced on an antenna structure by sources or incident fields. The approach has no theoretical limit and may be used for very large arrays or for the very fine subdivision of smaller arrays.
Nittany Scientific products contain enhanced versions of all NEC cores.
