The modeling challenge is that the ribbon operates in two different modes
at the same time: a radiating common mode with a velocity factor of say
0.95; and a non-radiating "stub" mode with a VF of about 0.8. The problem
is to model both modes simultaneously, for the whole string of stubs,
without changing the physical dimensions of the real antenna. I'm not
sure if NEC can do this, but maybe Roy can comment?
Thanks Ian, for the spelling and for jogging my memory on the
subject. I believe you have hit the nail on the head. EZNEC
apparently cannot "model both modes simultaneously".
