Antenna Modeling

EZNEC and 4nec2 are based upon the Numerical Electromagnetics Code, or NEC, which is a popular antenna modelling system for wire and surface antennas originally written in FORTRAN in the 1970s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. MMANA-GAL on the other hand is based upon MININEC which was written by John Rockway with support from Jim Logan.
