Mobile communication has grown explosively in recent years, leading to a strong demand for cheap, but high-performing bandpass filters with low insertion loss and smaller size. Surface acoustic wave (SAW) and thin film bulk acoustic wave (BAW) resonators r ...
Quality factor (Q) is an important property of micro- and nano-electromechanical (MEM/NEM) resonators that underlie timing references, frequency sources, atomic force microscopes, gyroscopes, and mass sensors. Various methods have been utilized to tune the ...
Visual tracking has become a very important component in computer vision, but achieving a robust, reliable and real time tracking remains a real challenge.In order to improve the actual state-of-the-art, we choose to study and improve one of the most perfo ...
An optical detector for detecting radio frequency (RF) signals, the optical detector comprising a light source and a photodetector, and an electrical circuit comprising a position dependent capacitor and a bias voltage source adapted for providing a bias v ...
Mass sensors, such as contour mode resonators are promising approach for biosensing in liquid environment. Their miniaturization offers many advantages, including small sample volume, rapid analysis, low power consumption, and integration of multiple devic ...
Nanoelectromechanical (NEMS) resonators have shown outstanding performance in mass sensing and heavy filtering applications due to their exceptional sensitivities and high quality factors. Examples of applications range from biomolecules/gas detection to e ...
In this report, the in uence of several geometric parameters on the performance of aluminum nitride (AlN) contour mode resonators (CMR) is investigated at dierent frequencies (182 MHz, 460 MHz and 570 MHz). Main in uence is the anchor width (Wa) and the an ...
This paper presents a design methodology for high quality factor resonators based on operational transconductance amplifier (OTA) employed in active filters. The quality factor of a resonator, as its main specification, is translated to the requirements of ...

We optimized the far-field emission pattern of one-dimensional photonic crystal nanobeams by modulating the nanobeam width, forming a sidewall Bragg cross-grating far-field coupler. By setting the period of the cross-grating to twice the photonic crystal p ...
We show the fabrication and characterization of a new generation of suspended microchannel resonators (SMRs) with integrated piezoelectric (PZE) actuation. We study resonance frequency, quality factor and frequency stability of singly-clamped hollow device ...
