Stochastic resonance in electrical circuits—I: Conventional stochastic resonance. [PDF]

open access: yes, 1999
Stochastic resonance (SR), a phenomenon in which a periodic signal in a nonlinear system can be amplified by added noise, is introduced and discussed. Techniques for investigating SR using electronic circuits are described in practical terms.

A Mass-In-Mass Metamaterial Design for Harvesting Energy at a Broadband Frequency Range

open access: yesEnergies, 2023
A novel deterministic method to harvest energy within a broadband frequency (0~25 kHz) from a mass-in-mass metamaterial is presented herein. Traditional metamaterials are composed of multiple materials (named as resonators and matrix) with different ...

A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]

open access: yes, 2014
An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...

Directional Transmission Characteristics of Acoustic Waves Based on Artificial Periodic Structures

open access: yesIEEE Access, 2019
Acoustic artificial periodic structures, also known as phononic crystal, have been widely used in special acoustic problems such as low-frequency vibration reduction and noise reduction due to their bandgap characteristics.

Broadband Air-Coupled Ultrasound Emitter and Receiver Enable Simultaneous Measurement of Thickness and Speed of Sound in Solids

open access: yesSensors, 2023
Air-coupled ultrasound sensors have advantages over contact ultrasound sensors when a sample should not become contaminated or influenced by the couplant or the measurement has to be a fast and automated inline process.

Binocular Localization Using Resonant Beam

open access: yesIEEE Transactions on Wireless Communications, 2023
Locating mobile devices precisely in indoor scenarios is a challenging task because of the signal diffraction and reflection in complicated environments. One vital cause deteriorating the localization performance is the inevitable power dissipation along the propagation path of localization signals.
