Numerical evaluation of potential integrals containing higher order hierarchical H(div) Legendre basis functions for parameterized quadrilateral surface cells
Author
Summary, in English
The singularity cancelation scheme initially introduced by Khayat
and Wilton for evaluating singular and near-singular potential
integrals with 1/R singularities has in this paper been
applied to parameterized quadrilateral cells containing higher order
hierarchical H(div) Legendre basis functions. The singular
and near-singular potential integrals treated in this paper appear
in the method of moment (MoM). Numerical results are presented for
different order numbers of the Legendre polynomials and for
quadrilateral cells of different shapes.
