Fig. 1. Illustration of the leaky-mode Bessel-beam launcher under considera- considera-tion
Fig. 2. (a) Normalized phase constant and (b) normalized attenuation constant vs. frequency f from DC to 100 GHz for the first TM modes of a  partially-open layered structure as in Fig
Fig. 3. Dispersion curves for the design of the higher-order launcher prototype. The operating points are given by the intersections of the fast leaky-wave modes and the hyperbolic curves given by the Bessel zeros
Fig. 5. Contour plot of the electric field |E z | along the ρz-plane for the mm-wave launcher under analysis at (a) f = 39.7 GHz, (b) f = 37.3 GHz, and (c) f = 40.3 GHz.
