The characteristics of two types of leaky modes on the asymmetric three-layered dielectric slab waveguide are fully investigated by solving the eigenvalue equation numerically. Loci of propagation constants and field distributions are presented and the effects of asymmetry on the propagation characteristics are discussed. It is found that the characteristics of substrate leaky modes are quite different from those of air leaky modes, and that the attenuation constants of substrate leaky modes become extremely small as the asymmetry becomes small.
