Rayleigh coefficient
WebThe eigenvalue relation (Rayleigh, 1894) is. Let αs ∼ 0.64 be the root of 1 - 2α + e -2α = 0. Then c is purely imaginary for 0 < α < α s with a maximum for α ∼ 0.40 and is real for α > … WebIn physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors.For example, it is used in optics to calculate the amount of light …
