We make an analytical study of the modal characteristic equation of a slab wa¨eguide with a flare bounded by two planes. We ( ) choose cylindrical polar coordinates , , z , and assume that the two bounding planes are extended infinitely in the z-direction, and are represented by s and s so that y is
