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 ...

Resonances and Resonant Fields in a Fabry-Perot Resonator Illuminated by a Line Source
Applied Optics, 1972In the present paper, the field internal to an infinite-strip plane-parallel mirror resonator is evaluated in the case when the structure is illuminated by a cylindrical primary wave. The feeder where the primary wave originates constitutes a perturbation of the resonator and is assumed to scatter a cylindrical wave proportional to the field impinging ...

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 ...

Resonances in scattering by a resonator
Let \(\Omega\) be an exterior of a bounded domain. The self-adjoint operator \(H=-\Delta\) with Dirichlet boundary conditions on \(\partial \Omega\) is studied in \(L^ 2(\Omega)\). A resonance \(\phi\in L^ 2(\Omega)\) is defined as a vector which is concentrated in some bounded domain \(B\subset \Omega\) and such that the spectral measure \((E_ H ...openaire +2 more sources

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 ...
