While many of the discussions on the list focus on the various incarnations of the Numerical Electromagnetics Code - Method of Moments (including NEC2, NEC4, MININEC, EZNEC, NECWin, and others), discussions related to RF coverage prediction (e.g., TIREM, ITS/ITM, and others), high-frequency codes (e.g., NEC-BSC), and other aspects of computational electromagnetics are most welcome.
