Not-so-resonant, resonant absorption
Physical Review Letters, 1987When an intense electromagnetic wave is incident obliquely on a sharply bounded overdense plasma, strong energy absorption can be accounted for by the electrons that are dragged into the vacuum and sent back into the plasma with velocities v\ensuremath{\simeq}${v}_{\mathrm{osc}}$.

The term resonant frequency embodies both technical and grammatical errors and its use should be deplored and deprecated. The proper form is resonance frequency.

Abstract This chapter aims to differentiate between two kinds of media use experiences that in the past twenty some years have uniformly been labeled entertainment experiences. In the background of four identified fundamental assumptions in entertainment theory (entertainment as reception phenomenon, disparity between what media users ...

Resonant frequencies of helical resonators
15th International Conference on Microwaves, Radar and Wireless Communications (IEEE Cat. No.04EX824), 2004The paper investigates the resonant frequencies of helical resonators. Full-wave 3D electromagnetic analysis is used to verify closed-form formulas known from literature. Corrections to formulas for dominant mode and new formulas for higher modes are proposed. Two-helical resonators filter was designed and measured.

ABSTRACT This article explores a state of movement in the humanities into nonhuman entanglements. A key term, “resonance,” emerges in this movement. Predominating scholarship orients resonance as a flourishing. In this article, accounts of the destructiveness of mechanical resonance signal a telling lacuna in humanities scholarship ...

On the tracking of resonance and antiresonance of a piezoelectric resonator
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1991A quantitative analysis of the tracking of the zero-phase resonance frequency, f(r), and antiresonance frequency, f(a), of a piezoelectric resonator reported previously by the author (1990) is presented. Integral and integrodifferential equations for the system angular frequency omega( t) are derived, and numerical calculations are carried out for a ...

Progress in Nuclear Magnetic Resonance Spectroscopy, 2014
Cavity resonators are widely used in electron paramagnetic resonance, very high field magnetic resonance microimaging and also in high field human imaging. The basic principles and designs of different forms of cavity resonators including rectangular, cylindrical, re-entrant, cavity magnetrons, toroidal cavities and dielectric resonators are reviewed ...

Primary resonance of piezoelectric resonators
1996 IEEE Ultrasonics Symposium. Proceedings, 2002It is found that the nonlinear behavior of piezoelectric resonators is more complicated than that predicted by previous theories. Actually the resonators work as parametrically excited vibration systems. Mode-coupled equations are obtained by means of the boundary integration. The method of multiple scales is used to solve the equations.

Resonances of a "Pillbox" Dielectric Resonator
1978 8th European Microwave Conference, 1978Resonant frequency, quality factor and field plots are discussed for a circular-cylindrical dielectric resonator. These quantities are calculated in the limit ?r ??. The method is a perturbation technique based on an expansion in the (small) parameter (1/??r).

Resonance Thrombography is a method to follow up the coagulation process ex vivo from its very beginning up to its final consolidation phase resp. fibrinolysis. The mode of measurement is adopting the resonance effect of fibrin elasticity. The connection of a cylindric rod and outer cylinder by elastic fibrin fibres will increase the potential natural ...
