UDC 621.396

T. V. Glotova, T.V.Melnikova

The features of the solution of the integral equations used in the solution of problems of scattering of electromagnetic waves are discussed. The main methods that used are noted. It is proposed to modify the usual method of moments, due to the choice of basis and test functions. Examples of test objects used for the calculations are given. It was found that the more complex the contour of the object, the worse the condition number of linear equations. That is, the scale of the investigated basis functions may not be large. It is shown that if the solution of the integral equation is almost a linear function, the size of the linear equations can be significantly reduced compared to the original.

Keywords: technical electrodynamics, the scattering of radio waves, method of moments, integral equation, numerical method.
