Abstract

In the last year's meeting we reported a novel approach for stabilization of numerical calculation of plasmonic propagation band structure. This method enables us to precisely obtain the propagation modes of periodically patterned two-dimensional conducting sheets, with arbitrarily high order of spatial harmonic content. Following the above contribution, we here present successful construction of a periodic fractal structure based on the combination of square array of wires and the space-filling Hilbert curves, leading to very large plasmonic gaps in the propagation spectrum. Different parameters affecting that gap, and the way to control each of them will be presented. Possible applications will be discussed.
