摘要

利用渐近波状边界条件分析了具有介质填充横向波状的左手矩形波导。推导了色散关系以及波导和波纹中的场表达式。与相当复杂的全波解相比，渐近解证明在宽频带内提供准确的结果。研究了渐近边界条件的局限性，确定了所提解的有效范围。

Application of the Asymptotic Corrugation Boundary Conditions to the Analysis of Composite Right/Left-Handed Corrugated Waveguide

The asymptotic corrugation boundary conditions are employed to analyze left-handed rectangular waveguides with dielectric-filled transverse corrugations. The dispersion relations as well as the field expressions in the waveguide and the corrugation are derived. Compared to the rather sophisticated full-wave solution, the asymptotic solution proves to provide accurate results within a wide frequency band. The limitations of the asymptotic boundary conditions are investigated to determine the range of validity of the presented solution.
