Comment on "Influence of bending on power distribution in step-index plastic optical fibers and the calculation of bending loss".
Arguments are presented that a recent paper on the topic of power distribution and mode coupling in curved step-index plastic optical fibers is incorrect and that the method proposed is conceptually flawed except for the special case when the fiber is straight, which was the case used to verify the calculations.
