THE RADIATION QUALITY FACTOR OF VERTICALLY POLARIZED SPHERICAL ANTENNAS ABOVE A CONDUCTING GROUND PLANE
Antennas
2014/12/8
The radiation quality factor of small vertically polarized antennas above a ground plane is investigated. Although the quality factor of small antennas in free space has been investigated extensively ...
Probability Distribution of the Quality Factor of a Mode-Stirred Reverberation Chamber
Probability Distribution Quality Factor a Mode-Stirred Reverberation Chamber
2012/11/23
We derive a probability distribution, confidence intervals and statistics of the quality (Q) factor of an arbitrarily shaped mode-stirred reverberation chamber, based on ensemble distributions of the ...
Fabrication and characterization of high quality factor silicon nitride nanobeam cavities
Fabrication characterization quality factor silicon nitride nanobeam cavities
2010/11/9
Si3N4 is an excellent material for applications of nanophotonics at visible wavelengths due to its wide bandgap and moderately large refractive index (n $\approx$ 2.0). We present the fabrication and ...
Spinning-in Fibres – a Quality Factor of Rotor Yarns
spinning-in of fibers open-end rotor-spun yarn carded cotton yarn
2009/2/13
The physical-mechanical properties of yarns, similar to those of other solid matters, are a function of their structure. Yarns are composed of fibres of different lengths and shapes, resulting in yarn...
Calculation of the external quality factor of the high power input coupler for the BEPCⅡ superconducting cavity
high power input coupler external quality factor superconducting cavity
2008/1/28
It is very important to predict the coupling between the cavity and the high power input source in the coupler design. In this paper, a time domain method is used to calculate the external quality fac...
