We show that high spectral sensitivity in surface plasmon resonance sensor is due to the multi-mode nature of the sensing scheme. Multi-mode sensing can be applied to dielectric systems to achieve similar extraordinary spectral sensitivity.
We analyze propagating plasmonic modes in deep-subwavelength coaxial metallic waveguides with a hollow core. Such modes couple to plane waves and exhibit much larger cutoff wavelengths than the TE11-mode in a conventional coaxial waveguide.
We report high transmission through SiC films when a two-dimensional periodic arrangement of subwavelength cylindrical holes is made. We attribute the near-perfect transmission peak inside the polariton gap of SiC to propagating waveguide modes.
We report a theoretical analysis on line defects in self-assembled photonic crystals. Several defect geometries have been considered in order to achieve a structure with a large single-mode bandwidth.
Summary form only given. Photonic crystals can be employed as the substrates of planar antenna to minimize or eliminate the radiation energy loss into the substrate. Previously, surface waves of two-dimensional (2D) photonic crystals has been studied in the case that a complete bandgap exists for only one polarization state. We study the surface waves of a 2D photonic crystal with a complete photonic...
