Highly-Sensitive and Frequency-Selective Imaging of Defects via Local Defect Resonance [PDF]
, 2014 In this paper, a consistent way to enhance acoustic, optical and thermal defect responses is suggested by using selective ultrasonic activation of defects based on the concept of local defect resonance (LDR).

Acoustic Focusing Imaging Characteristics Based on Double Negative Locally Resonant Phononic Crystal
IEEE Access, 2019 To achieve high-efficiency and high-resolution acoustic focusing, we used artificial periodic acoustic structures composed of cell arrays to manipulate the acoustic transmission wave front, and used finite element software to simulate the acoustic field ...

Local Chirality of Optical Resonances in Ultrasmall Resonators
Physical Review Letters, 2012 In wavelength-scale cavities with chiral-symmetric geometry, wave optical effects can introduce local chirality, that is, a spatial separation of the clockwise and counterclockwise propagating resonant modes. We show that this local chirality results in unidirectional lasing emission in the far field. In the presence of a waveguide, the local chirality

Stochastic resonance in electrical circuits—II: Nonconventional stochastic resonance. [PDF]
, 1999 Stochastic resonance (SR), in which a periodic signal in a nonlinear system can be amplified by added noise, is discussed. The application of circuit modeling techniques to the conventional form of SR, which occurs in static bistable potentials, was ...

Resonant Anderson localization in segmented wires [PDF]
Physical Review E, 2016 We discuss a model of random segmented wire, with linear segments of 2D wires joined by circular bends. The joining vertices act as scatterers on the propagating electron waves. The model leads to resonant Anderson localization when all segments are of similar length.

Localized and complete resonance in plasmonic structures [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2015 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 takes place whenever the resonance does and moreover, the power is always bounded and might go to ...
