Analysis of Graded-Index Fibers Using a Full-Wave Equivalent Circuit

This paper presents an efficient approach for the analysis of graded-index profile waveguides. The variation of the index of refraction is modeled considering a sufficient number of concentric dielectric layers, each with a different index of refraction. The propagation constant in the layered struc...

Zusammenfassung:	This paper presents an efficient approach for the analysis of graded-index profile waveguides. The variation of the index of refraction is modeled considering a sufficient number of concentric dielectric layers, each with a different index of refraction. The propagation constant in the layered structure is calculated by setting up a full-wave equivalent circuit, which allows the derivation of the system equation for the whole structure. Two examples are given, including validation with the commercial software Ansoft HFSS
