NEC-Win
Professional
was designed to provide an easy-to-use
tool for antenna designers that will
facilitate the design
and analysis process. The intuitive nature of the graphical
interface will help you produce outstanding results, fast! Features
like 3-D visualization, real time rotate, pan, and zoom with
the mouse, let you see more views of your design interactively.
Spread-sheet-style data entry of the wire coordinates, and
the copy, cut, and paste commands, make it simpler to place
your information into commercial spread sheet programs to
run formulas and variables. NEC-Win Pro encourages you to
push the design parameters to levels you may have been reluctant
to build and test in the past.
NEC-Win
Pro will display your radiation patterns on screen or print
in full color for presentations or review of your work. Plus,
you can save your screen, or a portion of it, as a bitmap
file to place into a word-processing program as a graphic
element. This powerful antenna design and analysis tool gives
you unmatched levels of performance and incredible options.
NEC-Win Pro is a dream come true for professionals in the
field.
Included
with NEC-Win Pro is a modified NEC2 core which has been optimized
for the 32 bit operating system. The core supports DMA (dynamic
memory allocation) and is capable of calculating the results for thousands of segments. If your computer has the resources
the core will use them.
What is the Frequency
Limitation of NEC ?
There is no limit on the
frequency range, although NEC is usually not used for
frequencies above 2 GHZ. NEC is dependent on the structure
geometry, not the frequency. If the structure can be modeled
following the NEC guidelines, than the appropiate frequency
can be used.
NEC-Win Pro Features
Full
NEC2 command set with dialog for each command
Frequency of up to 2 GHZ

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. The NEC-Win
products contain enhanced versions of all NEC cores.
