Abstract / Description:We numerically study the spectral response of 'U'-shaped
split-ring-resonators at normal incidence with respect to the resonator
plane. Based on the evaluation of the near-field patterns of the
resonances and their geometry-dependent spectral positions, we obtain a
comprehensive and consistent picture of their origin. We conclude that
all resonances can be understood as plasmonic resonances of increasing
order of the entire structure. In particular, for an electrical field
polarized parallel to the gap the so-called LC-resonance corresponds to
the fundamental plasmonic mode and, contrary to earlier
interpretations, the electrical resonance is a second order plasmon
mode of the entire structure. The presence of further higher order
modes is discussed. (c) 2006 Optical Society of America
