    Hello ALM,

     

    What exactly do you want to know? The short answer is that FEKO uses RWG basis functions and uses an adaptive weighting scheme (and not full Galerkin testing). FEKO also support higher order basis functions and many other specialisations. What do you want to do with the information? If we know the goal, we might be able to give you more specific answers.

    Hi !

    Thank you for your reply! the goal is that I should implement a Matlab code for simple structures and compare the output( eigenvalues , eigencurrents,..etc) with Feko . any suggestion would be very welcomed.

    In that case, I suggest you work with the original RWG paper (http://ieeexplore.ieee.org/document/1142818/ , S. M. Rao, D. R. Wilton, A. W. Glisson, 'Electromagnetic Scattering by Surfaces of Arbitrary Shape', IEEE Transactions on Antennas and Propagation, vol. AP-30, no. 3, pp. 409-418, May 1982). That is where I started.
