How It Works
The code is based on the method of moments solution of the electric field integral equation for thin wires and the magnetic field integral equation for closed, conducting surfaces. The algorithm has no theoretical limit and can be applied to very large arrays or for detailed modeling of very small antenna systems. NEC models can include wires buried in a homogeneous ground, insulated wires and impedance loads.
Models are defined as elements of wire or similar as an input text file (typically in ASCII). They are then input into the NEC application to generate tabular results. The results can then be input into subsequent 'helper' applications for visual viewing and the generation of other graphical representations as smith charts, etc.

Famous quotes containing the word works:
“Men seem anxious to accomplish an orderly retreat through the centuries, earnestly rebuilding the works behind them, as they are battered down by the encroachments of time; but while they loiter, they and their works both fall prey to the arch enemy.”
—Henry David Thoreau (1817–1862)
