WebDec 5, 2014 · The meaning of “normal” type is that it is a natural mode. This statement, known as Rayleigh's principle has been given the following interpretation by Temple and Bickley: In the fundamental mode of vibration of an elastic system, the distribution of kinetic and potential energies is such as to make the frequency a minimum. WebThe theory of backscattering in single-mode optical fibers is described through use of a correlation function for the refractive-index fluctuation in the fiber. A simple formula for the backscattered power is derived using two correlation functions for the Booker–Gordon and Gaussian models. The zeroth-order approximation of the formula, in which the correlation …
