Scattering from the PEC Flat Strip by Using the Method of Moments with Sinc Type Basis Functions

Abstract:
Using sinc methods is a very powerful technique in physics and mathematics. They give good accuracies and they’re easily implemented. Method of Moments (MoM) is used to transform linear operator equations to linear algebraic equations such as matrix equations. In this study, Galerkin’s procedure is applied in the MoM. Sinc type basis functions are chosen. In the final step integral equation is tested with sinc functions. Then the convolution property of the sinc functions is used. So the integral of the sinc function with an analytical function can be approximated with error criteria. Using this method provides an easily computed matrix equation and saves cpu time.
