Near-field characterization of 2D disk resonator on Bloch surface wave platform

Hans Peter Herzig, Myun Sik Kim, Elsie Barakat, Richa Dubey

We experimentally and theoretically investigate the characteristics of a two-dimensional (2D) disk resonator, which is fabricated on a Bloch surface wave platform. Such a platform is exploited to manipulate the surface waves by patterning nano-thin 2D opti ...

Floquet topological insulators for sound

Romain Christophe Rémy Fleury

The unique conduction properties of condensed matter systems with topological order have recently inspired a quest for the similar effects in classical wave phenomena. Acoustic topological insulators, in particular, hold the promise to revolutionize our ab ...

Acoustic dispersive prism

Juan Ramon Mosig, Hervé Lissek, Sami Driss Karkar, Seyyed Hussein Seyyed Esfahlani

The optical dispersive prism is a well-studied element, which allows separating white light into its constituent spectral colors, and stands in nature as water droplets. In analogy to this definition, the acoustic dispersive prism should be an acoustic dev ...

Parity-Time Symmetry in Acoustics: Theory, Devices, and Potential Applications

Romain Christophe Rémy Fleury

Parity-time (PT) symmetric systems based on bal- anced distributions of gain and loss have attracted significant attention in wave physics, enabling the possibility of compen- sating material losses in photonic systems, and of inducing ex- ceptional scatte ...

Graphene Based Mechanical Resonators Fabricated via Direct Dry Transfer

Luis Guillermo Villanueva Torrijo, Tom Larsen, Marco Di Gisi

We present here the fabrication of large suspended sheets of graphene for mechanical resonators. The diameter of the circular resonators varies from 1.2 μm to 26.5 μm resulting in diameter-to-thickness aspect ratios as large as 74000. The membranes were fa ...

Size-dependent sorting of C. elegans nematodes through an adjustable microfluidic filter structure.

Martinus Gijs, Thomas Lehnert, Matteo Cornaglia, Li Dong

We introduce a new and simple microfluidic sorting device based on adjustable filter structures that can be easily tuned by external pressure for a specific size-dependent C. elegans worm sorting experiment. A single device can be used for selecting and so ...

Reducing Energy Dissipation in ULP Systems: PLL-Free FBAR-Based Fast Startup Transmitters

Christian Enz, David Ruffieux, Raghavasimhan Thirunarayanan

The energy dissipated by conventional phase-locked-loop-based transmitters (TXs) during the long startup phase is a major bottleneck that reduces the energy autonomy of duty-cycled ultra-low-power systems. In order to tackle this problem, this paper presen ...

Optical-resolution photoacoustic imaging through thick tissue with a thin capillary as a dual optical-in acoustic-out waveguide

Demetri Psaltis, Christophe Moser, Nicolino Stasio, Emmanuel André Henri Bossy

We demonstrate the ability to guide high-frequency photoacoustic waves through thick tissue with a water-filled silica-capillary (150 mu m inner diameter and 30 mm long). An optical-resolution photoacoustic image of a 30 mu m diameter absorbing nylon threa ...
