Abstract:
|
The Method-of-Moment (MoM) discretization of the
Electric-Field Integral Equation (EFIE) for a transversal
electric (TE) illuminating plane wave impinging on an
infinitely long cylinder (2D-object) traditionally requires
continuous piecewise linear basis functions. These basis
functions are particularly convenient in the numerical
implementation because they reduce the degree of the Kernel
singularity. Recently, a nonconforming implementation of the
TE-EFIE discretized with discontinuous piecewise linear basis
functions has been successfully developed with the testing
procedure done over small surface entities attached to the
boundary of the object, inside the body under analysis. In this
paper we present a novel nonconforming discretization of the
TE-EFIE based on discontinuous piecewise linear basis
functions with a testing procedure that relies only on line
integrals. This allows for an easier and more efficient
computation of the impedance matrix elements while
preserving the improved far-field accuracy observed for sharp
edged objects in the previous surface-tested TE-EFIE
implementation. |
