Summary

 
The paper discusses construction of analytical approximation for currents needed to obtain dissipation diagrams for the fields of finite and infinite grids consisting of thin parallel perfect conductors and absorbers. Analytical approximation is asymptotic and based on the method of boundary integral equations assuming the existence of the low parameter, i.e. assuming that the ratio between the conductor radius and the wave length is much less than one. It is also assumed that the interaction between the conductors, in terms of contribution to the electric current, has the lower order than the main contribution induced by the falling plane wave. This assumption is quite correct if the distances between the conductors are equal to at least quarter-wavelength.
The algorithm obtained will allow faster and more efficient calculation of reflection coefficient for the falling field generated by a grid of thin conductors, as compared to existing numerical realizations for the method of boundary integral equations.
