Development of computational 3D MoM algorithm for nanoplasmonics
(2013-12) SOUZA, Nadson Welkson Pereira de; COSTA, Karlo Queiroz da; DMITRIEV, Victor Alexandrovich
In this paper, we present an algorithm for full-wave electromagnetic analysis of nanoplasmonic structures. We use the three-dimensional Method of Moments to solve the electric field integral equation. The computational algorithm is developed in the language C. As examples of application of the code, the problems of scattering from a nanosphere and a rectangular nanorod are analyzed. The calculated characteristics are the near field distribution and the spectral response of these nanoparticles. The convergence of the method for different discretization sizes is also discussed.

Resonant properties, of modified triangular plasmonic nanoparticles with higher field concentration
(2013-12) COSTA, Karlo Queiroz da; DMITRIEV, Victor Alexandrovich
In this paper, we present an analysis of the resonant response of modified triangular metallic nanoparticles with polynomial sides. The particles are illuminated by an incident plane wave and the method of moments is used to solve numerically the electromagnetic scattering problem. We investigate spectral response and near field distribution in function of the length and polynomial order of the nanoparticles. Our results show that in the analyzed wavelength range (0.5-1.8) µm these particles possess smaller number of resonances and their resonant wavelengths, near field enhancement and field confinement are higher than those of the conventional triangular particle with linear sides.
