Re: MoM method
hi,
you are trying to model the current using pulse basis functions. This should give you a problem, that at the connection between the elements there is a step discontinuity in the current, which is modeled by line charge (in 2d) or point charge in 1d.
so what do you mean by being incapable of expressing the charge density (it would be a delta function) since div(J) = -i*w*p, where p is the charge density. You have a discontinuity in J, this would give a delta in p.
You may better use rooftop basis functions, as a_ronagh said. You won't have the problem of the current discontinuity.
Hope this will help
Best Regards,
