Modeling of scattering characteristics of dielectric and plasmon particles of complex geometry

Highlights: • The method of the solution of vector diffraction problem for complex geometry particles is developed. • An efficient algorithm for construction of carriers of auxiliary sources is proposed. • Check of the optical theorem for particles with absorption is carried out. • Frequency dependences for silver multifoils of revolution are presented. • Resonances in silver multifoils of revolution are found. The vector problem of diffraction of the plane wave field and the field generated by a point source on a magneto-dielectric body of revolution is considered. The case when the dielectric permittivity of the body medium has a negative real part is investigated. An efficient algorithm for solving the problem of diffraction on various multifoils of revolution is proposed. Comparison the proposed method with two other methods is carried out. The numerical results presented in this paper concern the problem of plane wave diffraction on dielectric and plasmon multifoils of revolution and on oblate spheroids.
