Ray tracing analysis for media with nonhomogeneous indices of refraction.
A computer code with an excellent accuracy/speed ratio has been developed to determine ray trajectories in media with spatially varying indices of refraction. Using this system code, several Luneburg lens configurations have been analyzed for off-axis behavior. General features of these lens systems, which have not been extensively investigated previously, are described, and potential applications in the fiber-optics and microwave areas are discussed.
