    Simulation of surface plasmon polaritons

    The hunt is on for better plasmonic designs, and optical simulation software will play an important role.
    FIGURE 1. A full-wave finite-element analysis is done of electromagnetic waves that scatter off a metallic sphere. The electric-field variations make it necessary to use a fine mesh throughout the computational domain. As a consequence of the Nyquist-Shannon sampling theorem, each wavelength needs to be resolved with a minimum of two sampling points to avoid aliasing. In practice, this leads to a requirement of at least a handful of finite elements per wavelength in each spatial direction.
