Weak signal enhancement by non-linear resonance control in a forced nano-electromechanical resonator [PDF]
, 2019 Driven non-linear resonators can display sharp resonances or even multistable behaviours amenable to induce strong enhancements of weak signals. Such enhancements can make use of the phenomenon of vibrational resonance whereby a weak low-frequency signal applied to a bistable resonator can be amplified by driving the non-linear oscillator with another ...

Adjustable Plasmonic Core–Shell Nanoparticles for Personalized Color Vision Correction
Advanced Engineering Materials, EarlyView.This study introduces a personalized solution for correcting color vision deficiency (CVD) by embedding tunable core‐shell metal nanoparticles—a common nanotechnology—into contact lenses. By customizing the nanoparticles’ optical properties to filter specific wavelengths, these lenses address individual visual impairments, enhancing color ...

A miniature fractal-based dual-mode dual-band microstrip bandpass filter design [PDF]
, 2014 In this paper, a fractal-based complementary split-ring resonator (CSRR) has been introduced as a defected ground structure (DGS) in the ground plane of a dual-mode microstrip bandpass filter to produce a new compact filter with dual-band response.

Microwave Oscillator Design for a SRR Based Biosensor Platform
Proceedings, 2018 A sensor for biomedical markers based on a split ring microwave resonator (SRR) was developed. The surface of the microwave resonator is covered with receptors that specifically bind to the target proteins where the local permittivity is changed.
