We propose to funnel, select, and collect light spectrally by exploiting the unique properties of deep-subwavelength resonant apertures in a metallic film. In our approach, each aperture has an ...
Polished metallic surfaces exhibit a high degree of specularity, which makes them difficult to reproduce accurately. We have applied two different techniques for modelling a heritage object known as t...
We demonstrate efficient wireless power transfer between two high Q resonators,especially in a complex electromagnetic environment. In the close proximity of metallic plates, the transfer ef@...
Materials with simultaneous high electrical conductivity and optical transmittance are essential for various optoelectronic devices, such as touch-screen displays,[1–4] solar cells,[2,5–7] and organic...
Three heat sinks with porous-coated parallel microchannels were fabricated by using a solid-state sintering method. The enhanced flow boiling of anhydrous ethanol in the porous-coated microchannels wa...
The optical transmission properties of two types of photonic crystals have been analyzed by using the transfer matrix method. The first one is the dielectric photonic crystal (DPC), and the second is ...
Influence of duty ratio of metallic gratings applied in quantum well infrared photodetector (QWIP) with detection ranging from 3 μm to 5 μm was studied in this paper. The influence on longer enhanced ...
We numerically demonstrated that efficient wireless energy transfer can be achieved between two high Q resonators in a complex electromagnetic environment. In particular, in the close proximity ...
We demonstrate numerically, using a three-dimensional finite-difference frequency-domain method, the ability to design a phase front using an array of metallic pillars. We show that in such stru...
We theoretically investigate the enhancement of optical absorption in thin-film organic solar cells in which the top transparent electrode is partially substituted by a periodic metallic grating...
We investigate the use of nanopatterned metallic films as transparent conductive electrodes in optoelectronic devices.We find that the physics of nanopatterned electrodes, which are often ...
We experimentally demonstrate planar lenses based on nanoscale slit arrays in a metallic film. Our lens structures consist of optically thick gold films with micron-size arrays of closely ...
We consider an aperiodic array of coupled metallic waveguides with varying subwavelength widths.For an incident plane wave, we numerically demonstrate that a focus of as small as one-hundredth of a wa...
A metallic slot waveguide, with a dielectric strip embedded within, is investigated for the purpose of enhancing the optics-to-THz conversion efficiency using the difference-frequency generation...
We present theoretical considerations as well as detailed numerical design of absorber and emitter for Solar Thermophotovoltaics (STPV) applications. The absorber, consisting of an array of tungsten p...
