Design of Plasmonic-Waveguiding Structures for Sensor Applications

open access: yesNanomaterials, 2019
Surface plasmon resonance has become a widely accepted optical technique for studying biological and chemical interactions. Among others, detecting small changes in analyte concentration in complex solutions remains challenging, e.g., because of the need

Friction-Excited Oscillation of Air Conditioner Rotary Compressors: Measurements and Numerical Simulations

open access: yesLubricants, 2022
The oscillation of a rotary compressor was measured and analyzed in the frequency and time domains. The harmonic wavelet transform was used to dissolve the oscillation signal into a series of single-frequency components.

Mode coupling in solar spicule oscillations

open access: yes, 2015
In a real medium which has oscillations, the perturbations can cause the energy transfer between different modes. The perturbation interpreted as an interaction between the modes is inferred as mode coupling.

Interaction between negative and positive index medium waveguides

open access: yes, 2008
The coupling between negative and positive index medium waveguides is investigated theoretically in this paper. A coupled mode theory is developed for such a waveguide system and its validity is verified.

Stability and Dynamics of Three-mode Coupling in δ Scuti Stars

open access: yesThe Astrophysical Journal
Recent observations of δ Scuti stars find evidence of nonlinear three-mode coupling in their oscillation spectra. There are two types of three-mode coupling likely to be important in δ Scuti stars: (i) direct coupling, in which two linearly unstable ...
