The transfer-matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified medium; a stack of thin films. [ 1 ] [ 2 ] This is, for example, relevant for the design of anti-reflective coatings and dielectric mirrors .
The ray transfer matrix is [] = [/]. and so = + + = + = + =. Only the real part of 1/ q is affected: the wavefront curvature 1/ R is reduced by the power of the lens 1/ f , while the lateral beam size w remains unchanged upon exiting the thin lens.
Transfer-matrix method (statistical mechanics), a mathematical technique used to write the partition function into a simpler form. Transfer-matrix method (optics), a method to analyze the propagation of electromagnetic or acoustic waves through a stratified medium. Ray transfer matrix analysis in geometric optics, a mathematical method for ...
The transfer-matrix method is used when the total system can be broken into a sequence of subsystems that interact only with adjacent subsystems. For example, a three-dimensional cubical lattice of spins in an Ising model can be decomposed into a sequence of two-dimensional planar lattices of spins that interact only adjacently.
An example of interference between reflections is the iridescent colours seen in a soap bubble or in thin oil films on water. Applications include Fabry–Pérot interferometers, antireflection coatings, and optical filters. A quantitative analysis of these effects is based on the Fresnel equations, but with additional calculations to account ...
It can be made incredibly small using thin films of nanometer thicknesses. [ 6 ] A Fabry–Pérot etalon can be used to make a spectrometer capable of observing the Zeeman effect , where the spectral lines are far too close together to distinguish with a normal spectrometer.
Thin-film interference caused by water-lipid boundary. Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, increasing reflection at some wavelengths and decreasing it at others. When white light is incident on a thin film, this effect produces ...
In applied mathematics, the transfer matrix is a formulation in terms of a block-Toeplitz matrix of the two-scale equation, which characterizes refinable functions.
