Resonances of a "Pillbox" Dielectric Resonator

1978 8th European Microwave Conference, 1978
Resonant 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).

On Resonant tunneling

Surface Science Letters, 1982
Abstract Localized electron states in oxides adjacent to metals hybridize with conduction electron states forming interface states, which at the localized site have an amplitude resonantly enhanced over the amplitude of the conduction electron states.

Primary resonance of piezoelectric resonators

1996 IEEE Ultrasonics Symposium. Proceedings, 2002
It 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 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 ...

Anti-Resonance — Velocity Resonance

Mekhatronika, Avtomatizatsiya, Upravlenie, 2019
The task of the study is to establish the nature of mechanical resonance, namely, it is a resonance of forces or speeds. Two definitions are introduced. Definition 1. Resonance of forces is a resonance arising at a frequency ω = (k/m)0,5 in a mechanical system including an inert body and an elastic element, at which the reactive forces developed by ...

Parametric resonance

Computing in Science & Engineering, 1999
Computer simulation experiments are especially good tools for helping students understand basic principles of physics. In this a, I have developed a package of simulation programs called Physics of Oscillations. One of its programs is suited for examining the phenomenon of paramagnetic resonance in a linear system.

Resonance—Nuclear Magnetic Resonance

2019
In this chapter, we will consider the principles of nuclear magnetic resonance to see how it can be exploited to generate signals from within the body related to the presence and properties of water within tissues. We will explore how radiofrequency waves can be used to exploit resonance phenomenon of protons placed within a magnetic field and the ...

Resistant Resonances:

In the United States, engineering and mental health-care professionals increasingly collaborate to develop vocal biomarker artificial intelligence, technologies that can supposedly detect mental distress by analyzing the sounds of the voice alone. This article draws from ethnographic fieldwork with individuals typically excluded from dominant accounts ...
