A local plane wave analysis is employed to derive the ray power transmission and attenuation coefficients for refracting leaky rays on graded-index fibers. These coefficients also reduce to established forms for tunneling rays and are compared with modal attenuation coefficients in the limit of strongly refracting rays.
