摘要：

Most modes on partially dielectric-loaded open guiding structures are purely bound in some frequency range and leaky in another. The transition region between them is complicated and interesting, including a section where the dispersion curve doubles back, because it connects a complex nonspectral (leaky-wave) solution with a real spectral (bound-wave or surface-wave) solution. The physical nature of this type of transition region is first discussed qualitatively, where some anomalous features are considered; then numerical values are presented for a specific example, a recently proposed novel leaky-wave antenna structure.
