Experimental mode shape determination of a cantilevered hydrofoil under different flow conditions

The first three mode shapes of a cantilevered NACA0009 hydrofoil were experimentally investigated in air and under different flow conditions in a cavitation tunnel. First and second bending modes and first torsion mode were determined in resonance conditio ...

Harnessing the damping properties of materials for high-speed atomic force microscopy

Jürgen Brugger, Georg Fantner, Adrian Pascal Nievergelt, Blake William Erickson, Jonathan David Adams, Jonas Grossenbacher

The success of high-speed atomic force microscopy in imaging molecular motors1, enzymes2 and microbes3 in liquid environments suggests that the technique could be of significant value in a variety of areas of nanotechnology. However, the majority of atomic ...

Localized and Complete Resonance in Plasmonic Structures

Hoài-Minh Nguyên

This paper studies a possible connection between the way the time averaged electromagnetic power dissipated into heat blows up and the anomalous localized resonance in plasmonic structures. We show that there is a setting in which the localized resonance t ...

Wafer-Level Hysteresis-Free Resonant Carbon Nanotube Transistors

Mihai Adrian Ionescu, Ji Cao, Sebastian Thimotee Bartsch

We report wafer-level fabrication of resonant-body, carbon nanotube (CNT)field-effect transistors (FETs) in a dual-gate configuration. An integration density of >10(6) CNTFETs/cm(2), an assembly yield of >80%, and nanoprecision have been simultaneously obt ...

The use of selected neutron absorption resonance filters to suppress spurious events on hot neutron spectrometers

Henrik Moodysson Rønnow, Diane Virginie Marie Lançon

Resonant absorption can be used as a filter for high energy neutron spectroscopy. Here we report the transmission of eight thin foil filters: erbium, indium, iridium, dysprosium, hafnium, gadolinium, cadmium and samarium, measured using neutron time-of-fli ...

T0001 / MilliNewton force sensor / frequency bandwidth

Thomas Maeder

This document gives an approximate calculation of the frequency bandwidth of the MilliNewton – and serves as a starting point for calculations on other cantilever-type sensors. The mechanical resonance frequencies of MilliNewton are high, due to the very s ...

Integrated VCSEL-Microlens Scanner With Large Scan Range

Niels Quack

We present an integrated beam steering system with a microlens scanner and a vertical cavity surface-emitting laser (VCSEL) source. The scanner and the VCSEL are assembled with an alignment sphere process and with an accuracy of 121 ±7 μm defined by precis ...

Quantum-Limited Amplification and Parametric Instability in the Reversed Dissipation Regime of Cavity Optomechanics

Tobias Kippenberg, Vivishek Sudhir

Cavity optomechanical phenomena, such as cooling, amplification, or optomechanically induced transparency, emerge due to a strong imbalance in the dissipation rates of the parametrically coupled electromagnetic and mechanical resonators. Here we analyze th ...

Elasto-Dynamic Behavior of a Two-Dimensional Square Lattice With Entrained Fluid II: Microstructural and Homogenized Models

Alessandro Spadoni, Vladimir Dorodnitsyn

This paper presents a detailed study of the pressure waves and effective mechanical properties of a closed-cell cellular solid with entrained fluid. Plane-harmonic-waves are analyzed in a periodic square with a finite-element model of a representative-volu ...
