A discussion of how NEC4 does insulated wires (in short, by changing
the wave number of the propagation in the conductor) can be found in
the NEC4 Theory Manual. Search for NEC4TheoryMan.pdf and there's
several copies out there.
I suspect that EZNEC does it by a similar approach - changing the
length of the wire to a slightly shorter length to accommodate the
slower propagation in the insulated wire. That may have been done
semi-empirically
More from the User Manual (which is marked export controlled, but if you
have a copy, there's a short discussion of how it works)
