Light Absorber with an Ultra-Broad Flat Band Based on Multi-Sized Slow-Wave Hyperbolic Metamaterial Thin-Films
Here we realize a broadband absorber by using a hyperbolic metamaterial composed of alternating aluminum-alumina thin films based on superposition of multiple slow-wave modes. Our super absorber ensures broadband and polarization-insensitive light absorption over almost the entire solar spectrum, near-infrared and short-wavelength infrared regime (500–2500 nm) with a simulated absorption of ove...
متن کاملSlow light and band gaps in metallodielectric cylinder arrays.
We consider two-dimensional three-component photonic crystals wherein one component is modeled as a drude-dispersive metal. It is found that the dispersion relation of light in this environment depends critically on the configuration of the metallic and dielectric components. In particular, for the case of an incident electromagnetic wave with electric field vector parallel to the axis of the c...
متن کاملSlow-light, band-edge waveguides for tunable time delays.
We propose the use of slow-light, band-edge waveguides for compact, integrated, tunable optical time delays. We show that slow group velocities at the photonic band edge give rise to large changes in time delay for small changes in refractive index, thereby shrinking device size. Figures of merit are introduced to quantify the sensitivity, as well as the accompanying signal degradation due to d...
متن کاملSlow-light plasmonic metamaterial based on dressed-state analog of electromagnetically induced transparency.
We consider a simple configuration for realizing one-dimensional slow-light metamaterials with large bandwidth-delay products using stub-shaped Fabry-Perot resonators as building blocks. Each meta-atom gives rise to large group indices because of a classical analog of the dressed-state picture of electromagnetically induced transparency. By connecting up to eight meta-atoms, we find bandwidth-d...
متن کاملCompact triple-band metamaterial inspired monopole antennas
Here we present a comparison analysis on the single loop resonator (SLR) inspired triple-band monopole antennas. Two configurations with rectangular and circular shaped radiation patches are presented. Simultaneously, two feed techniques with coplanar waveguide and microstrip feeds are performed to drive the antennas. And the conventional planar monopole antennas without the SLRs are also analy...
