Compound resonance-induced coupling effects in composite plasmonic metamaterials

We study a compound plasmonic system composed of a periodic Au grating array placed close to a thin Au film. The study is not limited to normal incidence and dispersion diagrams are computed for a broad variety of parameters. In addition to identifying loc ...

Off-Axis Texture and Crystallographic Accommodation in Multicomponent Nitride Thin Films Deposited by Pulsed Magnetron Sputtering

Akshath Raghu Shetty

The study of texture in thin films is one of the possibilities to obtain information on the fundamental physical processes which govern the thin film growth. Near the substrate, the crystalline orientation of the coating layer will usually be influenced by ...

A time-domain recursive method to analyse transient wave propagation across rock joints

Jian Zhao

The present investigation is concerned with transient wave propagation in a rock mass with a set of parallel joints by using a recursive method. According to the displacement field of a rock mass with a set of parallel joints, the interaction between four ...

Photonic Nanojet engineering: Focal point shaping with scattering phenomena of dielectric microspheres

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We experimentally engineer Nanojets produced by dielectric spheres by varying the illumination and observe the effect with a high-resolution interference microscope (HRIM). Converging and diverging spherical wavefronts and Bessel- Gauss beams are considere ...

Excitation of plasmon and guided-mode resonances in thin film silicon solar cells

Franz-Josef Haug

Thin film silicon solar cells are an attractive option for the production of sustainable energy but their low response at long wavelengths requires additional measures for absorption enhancement. The most successful concepts are based on light scattering i ...

Excitation of guided-mode resonances in thin film silicon solar cells

Christophe Ballif, Franz-Josef Haug, Karin Söderström, Ali Naqavi

Thin film silicon solar cells are attractive for photovoltaics; however, the poor charge transport in this material requires that the devices are thinner than the absorption length. Adequate absorption can nevertheless be achieved by light scattering at te ...

Motion of Spin Polariton Bullets in Semiconductor Microcavities

Timothy Chi Hin Liew

The dynamics of optical switching in semiconductor microcavities in the strong coupling regime is studied by using time-and spatially resolved spectroscopy. The switching is triggered by polarized short pulses which create spin bullets of high polariton de ...

Discrete vs continuum level simulation of radiative transfer in semitransparent two-phase media

Sophia Haussener

The mathematical formulation of the continuum approach to radiative transfer modeling in two-phase semi-transparent media is numerically validated by comparing radiative fluxes computed by (i) direct, discrete-scale and (ii) continuum-scale approaches. The ...

State-resolved reactivity of CH4 on Pt(110)-(1 x 2): The role of surface orientation and impact site

Rainer Beck, Régis Bisson, Marco Sacchi

The reactivity of methane (CH4) on Pt(110)-(1×2) has been studied by quantum state-resolved surface reactivity measurements. Ground state reaction probabilities, S0(v=0) ~ S0(laser-off), as well as state-resolved reaction probabilities S0(2v3), for CH4 exc ...
