It is convenient to denote cavity frequencies with a complex number ~ = /, where = (~) is the angular resonant frequency and = (~) is the inverse of the mode lifetime. Cavity perturbation theory has been initially proposed by Bethe-Schwinger in optics [1], and Waldron in the radio frequency domain. [2]
a the wave amplitude of each frequency component in metres, k 1 and k 2 the wave number of each wave component, in radians per metre, and; ω 1 and ω 2 the angular frequency of each wave component, in radians per second. Both ω 1 and k 1, as well as ω 2 and k 2, have to satisfy the dispersion relation:
The propagation constant of a sinusoidal electromagnetic wave is a measure of the change undergone by the amplitude and phase of the wave as it propagates in a given direction. The quantity being measured can be the voltage , the current in a circuit , or a field vector such as electric field strength or flux density .

The wave equation of quantum mechanics is first order in the time; therefore, Huygens’ principle is correct for matter waves, action replacing time." This clarifies the fact that in this context the generalized principle reflects the linearity of quantum mechanics and the fact that the quantum mechanics equations are first order in time.
It can be parameterized in terms of either the loss angle δ or the corresponding loss tangent tan(δ). Both refer to the phasor in the complex plane whose real and imaginary parts are the resistive (lossy) component of an electromagnetic field and its reactive (lossless) counterpart.
Let (,) be a Riemannian manifold, denote by : the tangent bundle over .The Sasaki metric ^ on is uniquely defined by the following properties: . The map : is a Riemannian submersion.
The Great Wave: Price Revolutions and the Rhythm of History is a scholarly work by historian David Hackett Fischer, published in 1996 by Oxford University Press.. Hackett Fischer identified three complete monetary waves in European history, each consisting of a price revolution, featuring high inflation, followed by a war crisis, followed by a new equilibrium.
