Title: Ray model for transmission of infrared radiation through multibent cylindrical waveguides

An improved ray model for simulating the transmission of laser radiation through a metallic or metallic-dielectric multibent hollow cylindrical waveguide has been developed. It calculates the power transmission and the power density at any point along the curved waveguide, as a function of geometrical dimensions of the waveguide, coupling lens at the entrance, polarization (random, vertical, or perpendicular), and the 3-D trajectory of the waveguide. In this paper, the theoretical calculations are compared with the experimental results.
