The use of power transfer matrices in predicting system loss: theory and experiment
TLDR
In this article, the authors used power transfer matrices to track the evolution of power distribution in ray packets and measured the power transfer of two ray packets for a step index fiber.Abstract:
The phase space diagram for parabolic and step index fibers leads to a graphic representation of the bound, leaky, and refracted rays of ray theory. This concept is used to predict the attenuation of typical components of local area networks. The technique uses power transfer matrices to track the evolution of power distribution in ray packets. In particular, we predict and then measure the power transfer of two ray packets for a step index fiber. The comparison is encouraging.read more

Use of Mode Transfer Matrices in L.A.N. Loss Evaluation
TL;DR: In this paper, a method, using Mode Transfer Matrices (HIM) to characterize step index fiber components and predict local area network (LAN) power budget is presented, and the results show that this method is well adapted to describing modal power distribution variations.

On the accuracy of the WKB approximation in optical dielectric waveguides
TL;DR: In this article, the authors compared the results obtained from the zero-order WKB approximation with those obtained from geometrical optics and from more rigorous weakly-guiding LP mode theories in the cases of the step index and parabolic index profiles.
