Özet:

 

A numerical method of moments (MoM) solution is applied to the  electromagnetic scattering from a periodic finite conducting strip  array when the incident electromagnetic plane wave E and H  polarizations illuminate the grating.  For such grating strip  geometry, we deal with singular integral equations arising from  Neumann and Dirichlet boundary conditions.  MoM is applied using  band-limited sinc functions as basis and testing functions.  The  Galerkin approach is followed in MoM formulation.  The properties of  the sinc function, with the infinite integral, are exploited in the  computations of the main matrix elements.  Also, the error in our  approach goes to zero with increasing bandwidth or lower sampling  rate.  Results of our formulation are given as surface current  densities and far field scattered data.  Our data is also compared  with previous results available in the literature.
