Abstract:
|
The discretization in Method of Moments (MoM) of
the Electric-Field Integral Equation (EFIE) is traditionally
carried out by preserving the continuity of the normal component
in the expansion of the current across the edges arising from the
discretization. This allows the cancellation of the hyper-singular
Kernel contributions arising from the discretization of the EFIE.
Divergence-conforming sets, like the RWG set, appear then as
suitable
choices
to
generate
successful
MoM-EFIE
implementations. In this paper, we present a novel MoM-
discretization of the EFIE with the non-conforming monopolar-
RWG basis functions, with jump discontinuities in the expanded
normal component of the current. We show with RCS results that
the new EFIE implementation shows good agreement with the
traditional normal-continuous RWG-implementation. |
