Bloch vector dependence of the plasma frequency in metallic photonic crystals.

چکیده
In this paper, a wire mesh metallic photonic crystal is modelized as a stack of gratings of period d made of very thin infinitely metallic rods (the conductivity is assumed to be infinite) of radius a (a<>d) . We derive a very accurate formula for the cut wavelength and we show that the plasma frequency in wire photonic crystals depends upon the Bloch vector. This latest formula is checked numerically.

Using the transfer matrix method, the effect of temperature on thetransmission spectra of thermal tunable nano metallic photonic crystal filter has beeninvestigated. Three different materials H (high refractive index material), L (lowrefractive index material) and M as a metallic layer, have been used to make thisstructure. M layer is considered to be Silver. The complex refractive index of Sil...
متن کاملNonlinear Bloch waves in metallic photonic band-gap filaments
We demonstrate the occurrence of nonlinear Bloch waves in metallic photonic crystals PCs . These periodically structured filaments are characterized by an isolated optical pass band below an effective plasma gap. The pass band occurs in a frequency range where the metallic filament exhibits a negative, frequencydependent dielectric function and absorption loss. The metallic losses are counterba...

متن کاملNovel nonreciprocal materials based on magnetic photonic crystals
Magnetic photonic crystals are spatially periodic dielectric composites with at least one of the constitutive components being a magnetically polarized material. Magnetic polarization, either spontaneous or induced, is always associated with nonreciprocal circular birefringence (Faraday rotation), which can bring qualitatively new features to the electrodynamics of photonic crystals. If the geo...
متن کاملFabrication and properties of gallium metallic photonic crystals
Gallium metallic photonic crystals with 100% filling factor have been fabricated via infiltration of liquid gallium into opals of 300-nm silica spheres using a novel high pressure–high temperature technique. The electrical resistance of the Ga-opal crystals was measured at temperatures from 10 to 280K. The data obtained show that Ga-opal crystals are metallic network with slightly smaller tempe...
