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.engAcesso AbertoNanotecnologiaNanopartículas metálicasMateriais nanoestruturadosSistemas nanoeletromecânicosEspalhamento eletromagnético de metaisArtigo de Periódico
