Abstract
We propose and implement a new concept of the discrete sources method; by applying this concept, one can investigate dielectric scatterers with large wave numbers. It is shown that the total scattering cross section can be determined analytically by using the amplitudes of discrete sources. The numerical results are presented; they demonstrate a considerable gain obtained by using the new concept in comparison with the conventional concept.
