This paper discusses how adaptive integral method for solving the problem of scattering of electromagnetic waves on the object, which consists of several magneto-dielectric materials can be used. The integral equation to be solved with the help of this approach helps to eliminate resonance phenomena in dielectrics, and to obtain very accurate results. The method of moments is applied in order to carry out the process of discretization of integral equations is given and the resulting matrix system which is solved based on the iterative approach. As a result, the memory requirements is reduced to store intermediate results and to speed up matrix-vector multiplications. Numerical results that illustrate the accuracy and efficiency of this method are given.

Keywords: scattering of radio waves, method of moments, integral equation, magneto-dielectric materials, algorithm.
