Increasing of the accuracy of calculation of plane-parallel magnetic field in piecewise-homogeneous mediums by the double layer method

SLAE for the unknown values of density of double layer at use continuous piecewise-linear approximation is got by application of Ampere's circuital law in the integral form for circuits covering each segment of the boundary of partition of mediums. Application of this SLAE allows to reduce the volume of calculations in comparison with the collocation method of solution of integral equations.
