Abstract

This paper presents an iterative method based on the wave concept for investigation of structures including Non-linear components. The principle of the iterative method consists to establishing a relationship between incident and reflected waves in order to characterize the studied structure. A passage from frequency domain to time domain is used to describe the behavior of a non-linear transmission line (NLTL) including eight Varactor diodes. It is demonstrated that the NLTL plays the role of a delay time line (DTL). The reflected and transmission coefficients are determined. The numerical results are compared with published data. © 2006 Wiley Periodicals, Inc.
