Frequency and time domains interactions in nanophotonics

In this thesis, we discuss the problems of scattering and optical manipulation related to nanosystems of different complexities. The multipolar decomposition method is used to represent scattering processes in nanosystems as a series of elementary excitati ...

Surface-wave dispersion retrieval method and synthesis technique for bianisotropic metasurfaces

Olivier Martin, Karim Achouri

We propose a surface-wave dispersion retrieval method and synthesis technique that applies to bianisotropic metasurfaces that are embedded in symmetric or asymmetric environments. Specifically, we use general zero-thickness sheet transition conditions to r ...

Imaging complex objects using learning tomography

Michaël Unser, Demetri Psaltis, Alexandre Goy, Joowon Lim

Optical diffraction tomography (ODT) can be described using the scattering process through an inhomogeneous media. An inherent nonlinearity exists relating the scattering medium and the scattered field due to multiple scattering. Multiple scattering is oft ...

Learning Tomography Assessed Using Mie Theory

Michaël Unser, Demetri Psaltis, Joowon Lim

In optical diffraction tomography, the multiply scattered field is a nonlinear function of the refractive index (RI) of the object. The Rytov method relies on a single-scattering propagation model and is commonly used to reconstruct images. Recently, a rec ...

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 ...

State-to-state scattering of CH₄ from Ni(111) and Gr/Ni(111)

Maarten Eduard van Reijzen

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 ...

A novel method for the synthesis of solvent-free Mg(B3H8)(2)

Jianmei Huang

This communication presents a novel and solvent-free method to synthesise Mg(B3H8)(2) via the gas-solid reaction between B2H6 and Mg2NiH4, which overcomes the limitations of wet chemical methods requiring solvent removal. ...

A method for building a structure containing living cells

Matthias Lütolf, Andrea Negro

A composition comprising a first material and a second material, wherein said first material is cross-linkable by a first cross- linking reaction and said second material is cross-linkable by a second cross-linking reaction, wherein said first cross-linkin ...

Physical bounds on absorption and scattering for cloaked sensors

Romain Christophe Rémy Fleury

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 ...

[DEMO] Tracking Texture-less, Shiny Objects with Descriptor Fields

Pascal Fua, Vincent Lepetit, Kwang Moo Yi, Alberto Crivellaro, Yannick Verdie

Our demo demonstrates the method we published at CVPR this year for tracking specular and poorly textured objects, and lets the visitors experiment with it and with their own patterns. Our approach only requires a standard monocular camera (no need for a d ...
