Abstract:
|
Method-of-moment (MoM) implementations of the
Electric-field Integral Equation (EFIE) in the scattering analysis
of infinitely long (2D) or arbitrarily shaped (3D) conductors have
traditionally required, respectively, piecewise-continuous or
divergence-conforming basis functions. Recently, nonconforming
EFIE-discretizations, with no imposed interelement continuity of
current, have been developed by testing the fields over small
domains attached to the boundary interfaces, inside the body
under analysis. This involves surface or volumetric testing
integrals, respectively, for the 2D Transversal-Electric (TE) or
3D MoM-implementations of the EFIE. In this paper, we present
new nonconforming discretizations of the EFIE that rely on
testing integrals over the boundary interface around the object;
namely, line-integrals or surface-integrals, respectively, for the
2D or 3D cases. We show with RCS results that these new, easierto-implement,
nonconforming discretizations of the EFIE provide
improved accuracy with respect to the traditional conforming,
piecewise-linear (2D) or RWG (3D), EFIE-implementations. |
