Resonant frequency of dielectric resonator

Proceedings RAWCON 98. 1998 IEEE Radio and Wireless Conference (Cat. No.98EX194), 2002
In this paper, an effective dielectric constant (EDC) has been introduced in an axial attenuation constant of dielectric waveguide model (DWM) method to calculate more accurately the resonant frequency of the TE/sub 01/spl delta// mode of a dielectric resonator (DR) in an MIC environment.

Frequency dependence of resonant tunneling

AIP Conference Proceedings, 1990
The time scale in coherent resonant tunneling is investigated by calculating the Ohmic conductance versus frequency, in one-dimensional single-electron terms, for a resonant-tunneling diode. When the Fermi level is at the resonance energy, the conductance rolls off near the frequency equal to (resonance width)/(Planck’s constant).

Off-resonance frequency filtered magnetic resonance imaging

Magnetic Resonance Imaging, 2010
One of the main problems with rapid magnetic resonance imaging (MRI) techniques is the artifacts that result from off-resonance effects. The proposed off-resonance frequency filtered MRI (OFF-MRI) method focuses on the elimination of off-resonance components from the image of the observed object.

The Resonance Frequency

Proceedings of the 2nd International Conference on Biomedical Signal and Image Processing, 2017
Cancer cell morphological, geometric and mechanic characterization could be important in relationship to therapy modality used. The objective of this work was to analyze the correlation between cell size and low intensity ultrasound sonication frequency for attached and floating cells.

Resonance frequency in patellar tendon

Scandinavian Journal of Medicine & Science in Sports, 2007
The aim of this study was to the measure resonance frequency of the patellar tendon in order to determine whether the resonance frequency exists in the soft tissue of the human body. A vibrator was attached to the medial aspect of the tibia of 10 healthy subjects to provide different frequencies of vibration, and an accelerometer was attached to the ...

Resonant frequencies of standing humans

Ergonomics, 1997
Many forms of industrial illness are thought to result from the effects of vibration on the human body. Prolonged exposure causes undue stress and discomfort. At the human whole-body resonant frequency there is maximum displacement between the organs and the skeletal structure and thus this is one frequency of vibration that should be minimized in the ...

Enhancement resonators for frequency combs

2006 IEEE LEOS Annual Meeting Conference Proceedings, 2006
The development of high finesse resonators for broadband frequency combs enabled the extension of the versatile frequency comb technique into the extreme ultraviolet with all its implications. We describe new developments in this field.

Audio-frequency Nuclear-resonance Echoes

Nature, 1957
THE principal expense and source of difficulty in equipment for nuclear magnetic resonance is the magnet to provide the large magnetic field. It has been shown that a nuclear-resonance signal can be obtained using only the Earth's field1,2. This is the so-called free-precession experiment, in which the nuclear system is first polarized at right angles ...

Prediction of ulnar resonant frequency

Journal of Biomechanics, 1975
Abstract As an extension of a previously reported study, 3 models were evaluated for prediction of ulnar resonant frequency given length, mineral content, and width in 210 subjects. The ulna was modeled as a homogeneous, isotropic cylindrical tube. For 2 of the models, the ulna was attached to rigid supports at each end—one by hinges (Model I) and ...

Resonant Frequency Avoidance

SAE Technical Paper Series, 2015
<div class="section abstract"><div class="htmlview paragraph">One major problem that any product (say Motor, engines etc.) which converts electrical energy into a mechanical energy would have is resonance. It has tendency to damage any material when the products operating frequency matches the resonant frequency.</div><div class ...
