    Enhanced backward scattering by surface plasmons on silver film

    Surface plasmon and its potential application in nanotechnology have attracted a remarkable amount of attention recently due to their novel properties. In this work we present an angularly resolved surface pla...

    Optical metamaterials at near and mid-IR range fabricated by nanoimprint lithography

    Two types of optical metamaterials operating at near-IR and mid-IR frequencies, respectively, have been designed, fabricated by nanoimprint lithography (NIL), and characterized by laser spectroscopic ellipsome...

    Symmetric and antisymmetric modes of electromagnetic resonators

    In this paper, we numerically study a new type of infrared resonator structure, whose unit cell consists of paired split-ring resonators (SRRs). At different resonant frequencies, the magnetic dipoles induced ...

    Experimental study of transmission enhancement of evanescent waves through silver films assisted by surface plasmon excitation

    In this paper, we investigated an essential precursor of superlensing: enhancing the transmission of evanescent waves assisted by excitation of surface plasmon. Using natural roughness as a well characterized ...

    Diffusion-limited photopolymerization in scanning micro-stereolithography

    The trade-off between process speed and resolution in microstereolithography (μSL) roots on the diffusion-limited kinetics of photopolymerization. Using a numerical model, we have investigated the influence of...

    Brownian motion of suspended particles in an anisotropic medium

    Some experimental results in the case of anisotropic media are at variance with the Einstein-Stokes formula of Brownian motion and the Singwi-Sjölander model. The disagreement comes from the anchor effect. The...
