A chip-size vertically aligned nanowire (NW) resonator arrays (VNRs) device has been fabricated with simple one-step lithography process by using grown self-assembled zinc oxide (ZnO) NW arrays. VNR has cantilever diameter of 50 nm, which breakthroughs smallest resonator record (>100 nm) functioning in atmosphere. A new atomic displacement sensing method by using atomic force microscopy is deve...

Abstract—A novel dual-mode bandpass filter (BPF) using stubloaded defected ground open-loop resonator is proposed in this article. Defected arrow-shaped stub is loaded to a defected ground openloop resonator, and two non-degenerate modes are excited for dualmode characteristics. Based on evenand odd-mode theory, dualmode characteristics of the resonator is analyzed. Design equations for the def...

QUANTUM AND CLASSICAL DESCRIPTION OF SPIN SYSTEMS WITH APPLICATION TO COHERENT RELAXATION IN A RESONATOR Andrey Klots April 1,2011 This paper describes effects of the interaction between the spin system and the resonator in magnetic resonance. In NMR the resonator circuit can provide feedback to the system of spins, which can lead to unusual effects, such as increasing dipole interactions and m...

An all-fiber-ring resonator has been constructed using a single strand of single-mode optical fiber and a directional coupler. Derivation of the resonator finesse in terms of fiber and directional coupler parameters is given. A finesse of 80 has been achieved experimentally. Applications of such a fiber-ring resonator are discussed.

In acoustic energy, harvesting energy is captured from external noise sources, controlled and stored for various applications. Despite the prevalence of acoustic energy a major challenge of energy harvesting is the low power density. Acoustic Energy Harvester consists of a resonator, an acoustic transducer and a storage device. When acoustic resonator is excited by an incident wave at its reson...

A high-sensitivity detection method for optical power fluctuations is demonstrated based on photodetection in reflection of an optical resonator with a specific impedance matching. That resonator is used to reduce the carrier power reflected by the resonator while preserving the power fluctuation sidebands for frequencies above the resonator bandwidth. A sensitivity of 7 x 10(-10) Hz(-1/2) for ...

The quantum-cascade laser can be used as an infrared source for a small portable photoacoustic trace gas detector. The device that we describe uses a quantum-cascade laser without collimating optics mounted inside an acoustic resonator. The laser is positioned in the center of a longitudinal resonator at a pressure antinode and emits radiation along the length of the resonator exciting an axial...

Use of microwave resonator-based sensors is a relatively new approach for the detection of biological reagents. Sensing mechanism is based on the tracking of the resonant frequency on electromagnetic resonator. Resonant frequency depends on structure geometry and material but is also affected by secondary changes in environment. Addition of a reference resonator to suppress these effects is pro...
