  • Abstract
    The letter considers a W-type slab waveguide in which a number of modes propagate. The significant feature is found to be the mode reservoir effect of a ray temporarily transformed into a leaky ray, owing to imperfections of the guide. Such disturbances cause little radiation loss if they are localised within the attenuation length of the leaky ray.
