Teaching Application of MATLAB Fuzzy Logic Toolbox to Modeling Coplanar Waveguides

Abstract

Adaptive neuro-fuzzy inference systems (ANFIS) have recently gained attention as fast and flexible vehicles to microwave modelling, simulation, and optimization. This article presents an initiative to teach the concept of modeline coplanar waveguides(CPWs) in the fuzzy logic toolbox of MATLAB to the electrical engineering students, The approach was based on illustrative applications that highlight the performance of ANFIS in the computation of the parameters of the microwave component,,. Following a brief description of CPWs, applications of the ANFIS modeling to the CPWs were done by means of a series of MATLAB functions. The author suggests that the use of MATLAB exercises will assist the students in gaining a better understanding of modeling CPWs by the use of ANFIS. (c) 2008 Wiley Periodicals, Inc.
