Abstract :
Several local (cell-by-cell) error estimation techniques for use with the electric field integral equation (EFIE) for TE-to-z polarization are proposed. These error estimators are evaluated for use in adaptive refinement in the locally-corrected Nyström (LCN) solution of the EFIE for various problems with localized high-error regions. The error estimation schemes are shown to correctly identify the high-error regions.
