Abstract : This manual assists the user with the operation of the Numerical Electromagnetic (EM) Engineering Design System (NEEDS 3.1). The Numerical Electromagnetic Code - Method of Moments (NEC-MoM), Version 4.0, is the principal computational tool for determining the shipboard EM environment in the high frequency through very high frequency bands. The use of NEC-MoM for antenna system and EM environment evaluation is a lengthy, tedious, and error prone process. NEC-MoM requires rigidly defined inputs and produces large masses of output data. NEEDS 3.1 was developed to assist in making the method of moment process less tedious and more error free.
