Light Scattering Enhancement at the Absorption Edge in Dewetting Droplets of Cyanine Dyes
Frank Nüesch, Jakob Heier, Florent Alexandre Boudoire
Diffraction properties of thin films of dewetted cyanine dye droplets are investigated and related to the complex refractive index. Strong changes in the index of refraction are often found near the absorption edge of organic dyes. Within a small window of ...
Wiley-V C H Verlag Gmbh2017State-to-state scattering of CH₄ from Ni(111) and Gr/Ni(111)
In this thesis, I describe the design and implementation of the first state-to-state surface scattering experiments for methane from clean single crystalline surfaces in ultrahigh vacuum. The experiments use infrared laser pumping to prepare the incident C ...
EPFL2016Physical bounds on absorption and scattering for cloaked sensors
We derive and discuss general physical bounds on the electromagnetic scattering and absorption of passive structures. Our theory, based on passivity and power conservation, quantifies the minimum and maximum allowed scattering for an object that absorbs a ...
2014Building and Testing a Prototype For CAMEA
CAMEA (Countinuous Angle Multiple Energy Analyser) is a new concept for analysing inelastically scattered neutrons with high efficiency. It contains many (up to 10) vertically focusing analyser arrays behind each other, analysing the scattered neutrons wit ...
2014CAMEA: Comparison to the Colder Chopper Spectrometer
The Cold chopper and CAMEA spectrometers are in many ways equivalent. One uses several incoming energies combined with a continuous outgoing energy band while the other use a continuous incoming band and several outgoing energies, and both have big angular ...
2014Passivity Limitations on Absorption Properties of Low-Scattering Objects
We analyze the constraints governing absorption and scattering of arbitrary sensors or receiving antennas. Our findings bring forward interesting physical limitations on the amount of accessible absorption in a low-scattering sensor and suggest practical w ...
2013Modeling (non-)uniform scattering distributions in geometrical acoustics
In most cases, a surface is not ideally smooth. It rather contains regular and irregular dents, bumps and other textures that influence the reflection of the incident wave. A reflection on such a corrugated surface causes a frequency-dependent redirection ...
Acoustical Society of America2013Experimental visualization of scattering at defects in electronic transport through a single atomic junction
For electronic transport at the nanoscale, coherent scattering at defects plays an important role. Therefore, the capability of visualizing the influence of defects on the conductivity of single atomic junctions may benefit the development of future nano-e ...
Amer Physical Soc2013Comparison of scattering and reflection SFG: a question of phase-matching
Sylvie Roke, Hilton Barbosa De Aguiar, Rüdiger Scheu, Kailash Chandra Jena
We present a comparison between sum frequency scattering (SFS) and reflection mode sum frequency generation (R-SFG). We have used scattering theory to describe both scattering experiments as well as reflection mode experiments. The interfacial vibrational ...
2012Certified reduced basis method for electromagnetic scattering and radar cross section estimation
Jan Sickmann Hesthaven, Yvon Maday
We study nontrivial applications of the reduced basis method (RBM) for electromagnetic applications with an emphasis on scattering and the estimation of radar cross section (RCS). The method and several extensions are explained with two examples with diffe ...
