EE 541, Fall 2009: Course Notes #2Scattering Parameters: Concept, Theory, and Applications Dr. John Choma Professor of Electrical Engineering University of Southern California Ming Hsieh Department of Electrical Engineering University Park: Mail Code: 0271 Los Angeles, California 90089–0271 213–740–4692 [USC Office] 213–740–8677 [USC Fax] [email protected]ABSTRACT: This report introduces the scattering parameter concept from two perspectives. First, the scattering parameters are shown to be an effective vehicle for charac-terizing the high frequency I/O characteristics of two port networks. Such meas-urement effectiveness derives from the fact that scattering parameter measure-ments obviate problems invariably incurred at very high frequencies by the actions of either short-circuiting or open circuiting network ports. The second perspective is the utility of scattering analyses in the design of lossless two port filters, which are fundamental to modern communication systems. Original: November 2002
