Optothermal shaping of lamb waves with square and spiral phase fronts

Romain Christophe Rémy Fleury, Janez Rus, Aleksi Antoine Bossart

We introduce a Lamb-wave medium with tunable propagation velocities, which are controlled by a two-dimensional heating pattern produced by a laser beam. We utilized it to demonstrate that waves in an appropriately designed medium can propagate in the form ...

Subwavelength imaging using a solid-immersion diffractive optical processor

Demetri Psaltis, Carlo Gigli, Niyazi Ulas Dinç, Yang Li

Phase imaging is widely used in biomedical imaging, sensing, and material characterization, among other fields. However, direct imaging of phase objects with subwavelength resolution remains a challenge. Here, we demonstrate subwavelength imaging of phase ...

Beam Loss Simulations for the Proposed TATTOS Beamline at HIPA

Mike Seidel, Hui Zhang

IMPACT (Isotope and Muon Production with Advanced Cyclotron and Target Technologies) is a proposed initia- tive envisaged for the high-intensity proton accelerator fa- cility (HIPA) at the Paul Scherrer Institute (PSI). As part of IMPACT, a radioisotope ta ...

Benchmark exercise on image-based permeability determination of engineering textiles: Microscale predictions

Véronique Michaud, Baris Çaglar, Guillaume Clément Broggi

Permeability measurements of engineering textiles exhibit large variability as no standardization method currently exists; numerical permeability prediction is thus an attractive alternative. It has all advantages of virtual material characterization, incl ...

Topology Optimization of an Electromagnet Manipulator for 3D Uniform Magnetic Field Generation

Yves Perriard, Adrien Jean-Michel Thabuis, Xiaotao Ren, Maribel Caceres Rivera

Magnetic manipulation is a method used for biomedical applications to remotely control micro-robots in a contactless manner. The electromagnet manipulator should control a magnetic field with 3 degrees of freedom inside a region of interest. In various cas ...

Computational Design of Flexible Planar Microstructures

Mark Pauly, Francis Julian Panetta, Tian Chen, Christopher Brandt, Jean Jouve

Mechanical metamaterials enable customizing the elastic properties of physical objects by altering their fine-scale structure. A broad gamut of effective material properties can be produced even from a single fabrication material by optimizing the geometry ...

Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers

Romain Christophe Rémy Fleury, Hervé Lissek, Stanislav Sergeev

Controlling audible sound requires inherently broadband and subwavelength acoustic solutions, which are to date, crucially missing. This includes current noise absorption methods, such as porous materials or acoustic resonators, which are typically ineffic ...

A universal route to efficient non-linear response via Thomson scattering in linear solids

Gabriel Aeppli, Ji Zhou, Cheng Wang, Junjie Li, Joe Martin Bailey, Min Chen

Non-linear materials are cornerstones of modern optics and electronics. Strong dependence on the intrinsic properties of particular materials, however, inhibits the at-will extension of demanding non-linear effects, especially those second-order ones, to w ...
