Locally Resonant Sonic Materials

Science, 2000
We have fabricated sonic crystals, based on the idea of localized resonant structures, that exhibit spectral gaps with a lattice constant two orders of magnitude smaller than the relevant wavelength. Disordered composites made from such localized resonant structures behave as a material with effective negative elastic constants and a total wave ...

Bidirectional Resonant Propulsion and Localization for AUVs

2020 IEEE International Conference on Robotics and Automation (ICRA), 2020
Battery life, reliability, and localization are prominent challenges in the design of autonomous underwater vehicles (AUVs). This work aims to address facets of these challenges using a single system. We describe the design of a bidirectional resonant pump that uses a single electromagnetic voice coil motor (VCM) capable of rotation around a central ...

Localized plasmon resonance

Nanotechnologies in Russia, 2017
A new analytical solution of the Helmholtz equation in spherical coordinates for an infinite homogeneous space, as well as the solution of the boundary problem for a piecewise-homogeneous medium (space divided into homogeneous domains with various dielectric permittivities of the spherical symmetry borders) has been obtained.

Localization of local anesthetic solution by magnetic resonance imaging

Ophthalmology, 2004
The aim of this study was to examine the distribution of local anesthetic solution by magnetic resonance imaging (MRI) after combined peribulbar and retrobulbar, superomedial retrobulbar, and sub-Tenon's injection in relation to clinical akinesia.Randomized clinical trial.Fifteen patients scheduled for cataract surgery, 5 patients in each group.Five ...

Internal Resonance and Localization in Micro-Resonator Arrays

Volume 5: 6th International Conference on Multibody Systems, Nonlinear Dynamics, and Control, Parts A, B, and C, 2007
Intrinsic Localized Modes (ILMs) are localization caused by intrinsic nonlinearities within an array of perfectly periodic oscillators. This localization phenomenon is studied in the context of arrays of coupled micro-scale cantilevers and of coupled piezoelectric micro-scale resonators.

On the localization of resonances

International Journal of Quantum Chemistry, 1987
AbstractThe notion of resonances in different settings is discussed. Two methods for localizing the resonances in the complex plane are given and applied to model potentials.
