Abstract

The description of the discrete Shifrin's method (DShM) is presented. This method is based on representation of monochromatic Maxwell's equations in integral form. Using a simple discretization scheme the corresponding integral equation is converted to a system of simultaneous algebraic equations which is solved by the successive approximation method. The accuracy and the worked area of the DShM were investigated by comparison with Mie theory for homogeneous sphere. It was shown that this method converges rapidly for optically soft particle, whose equivolumetric radius is of the incident radiation wavelength order. Two normalized scattering matrix elements, S₁₂/S₁₁ and S₃₄/S₁₁, for randomly oriented homogeneous finite cylinders are also presented as a practical example.
