In this article, a frequency-tunable 150W harmonic-tuned power oscillator is presented. The harmonic-tuned power amplifier of the oscillator was designed for improving drain efficiency with a single laterally diffused metal oxide semiconductor transistor using a nonlinear harmonic balance simulation code....
(07C914) Frequency-tunable perpendicular spin torque oscillator We present an experimental study on the frequency tunability of a perpendicular spin transfer torque oscillator with a perpendicularly magnetized (Co/Pd)_5... CH Sim,M Moneck,T Liew - Conference on Magnetism & Magnetic Materials: ...
The frequency-tunable modes additionally show a significant intensity modulation (IM). For example, spectral lines B, C, D that show a 20 GHz mode-hopping tuning range have a periodic intensity maximum modulation of −28 dB. By contrast, the two most intense emission peaks at 3.11 and...
The frequency-tunable differentially fed rectangular dielectric resonator antenna (DRA) loaded by chip capacitors or chip varactors is investigated. Two conducting strips are attached on two opposite DRA side walls for soldering the loading elements. In each loading case, a frequency-tunable DRA with ...
This paper introduces a frequency-tunable spectrometer, able to perform measurements in the range of 100 Hz - 24kHz. Keywords: magnetic particle imaging; magnetic particle spectroscopy; tunable-frequency; magnetic nanoparticles; particle parameters; image quality 1 Introduction In 2005 the upcoming ...
A frequency-tunable resonator comprises a basic element having at least one piezoelectric layer and at least one semiconducting layer. The electrodes, formed on main surface situated opposite one another of the basic element, are loaded with an external voltage, whereby the resonant frequency of the...
Ronald M. Lees2 & Li-Hong Xu2 Lamb-dip spectroscopy of the C−N stretching band of methylamine has been systematically extended to P-, Q-, and R-branch by using microwave sidebands of a large number of CO2 laser lines as frequency-tunable infrared sources in a sub-Doppler spect...

Namely, the dynamic performance of the tunable AMM presented in this paper can be adjusted simultaneously by tuning gauge pressure and gas temperature. Low-frequency (<500 Hz) vibration and noise attenuation is a goal of environmental and architectural engineering. However, in this frequency range,...
