Weighting the expansion coefficients with a suitable window function compensates for the computed field errors that occur because of the open surfaces. Numerical simulations demonstrate that the equivalent surface currents expanded with low-ordered basis functions on an open surface and weighted by suitable functions can be used to obtain the correct electromagnetic fields in a limited volume near the surface.EnglishBasis functionsClosed surfacesEquivalence principlesEquivalence theoremExpansion coefficientsField errorsSurface currentWindow functionsElectromagnetic fieldsComputational electromagneticsConference Paper10.1109/CEM.2013.6617119
