Abstract :
A transverse electric (TE) and magnetic (TM) wave diffraction problems on pre-fractal impedance strips are considered in this paper. This type of problems leads to boundary integral equations (IEs) with logarithmic singularities. A discrete mathematical model of the boundary IEs has been developed with the help of special quadrature formulas with the nodes in the nulls of Chebyshev polynomials. This research is completely aimed at performing numerical experiments with the help of an efficient discrete singularities method (DSM).
