How does EZNEC make its calculations? If you don't know you are

It uses the Moment Method (MM) sometimes called the Method

Each segment in EZNEC is assumed to have constant current.
In the aforementioned 8-sided coil, there are 200 segments,
each with an assumed constant current. The standing wave
current in each segment depends upon where it is inserted
in the standing wave environment as shown at:
