On the Effective Dielectric Constants of a Cylindrical Coplanar Waveguide with an Interior Layered Medium

具內部多層介質之柱面式共面波導之等效介電常數

摘要


本文將探討內部多層介質對柱面式共面波導傳播特性的影響,本研究採用嚴謹的全波分析方法來建構一個磁場積分方程式,再利用矩量法求得其數值解。在封閉金屬圓柱內部與外部把磁場與磁流拉上關係的兩種譜域格林函數已被成功的推導出來。在數值計算中,未知的磁流是以已知的全域基底函數來展開。本文就某些結構發表了色散特性的結果,並盡可能的與文獻中的已知結果做比較。

The objective of this research is to study the effects of the interior multilayered medium on a cylindrical coplanar waveguide (CPW). A rigorous full-wave analysis is applied to formulate a magnetic-field integral equation, which is subsequently solved numerically using the method of moments. Two spectral domain Green's functions that relate the magnetic fields to the magnetic currents just inside and outside the complete conducting cylinder are derived. Entire-domain basis functions for the surface magnetic currents are employed in the numerical computation. Results for the dispersion characteristics of some sample structures are presented and, wherever possible, are compared with data available in the literature.
