This paper considers the scattering of radio waves on the combined object consisting of several components. One of the possible ways, which is analyzed by the application of the method of integral equations. But with a large size of circuits and an increase in the number of components the time required for calculations increases significantly. In this regard, the iterative method is considered, which takes into account only the currents that are related directly to the reflection between components, which leads to a reduction in the size of the matrix of linear equations and an overall reduction in the computation time. Given an example, when as a combined object is a combination of two-dimensional elliptic cylinders. Characteristic size at which the iterative method works well.
