Abstract

Abstract: This paper presents one kind of sampler formed by the cascade network with three segments, and discusses the decomposing cascade network method with the linear fraction transformation. By using the odd-even mode method, the electro-magnetic parameters of the material under test are easy to obtain. The method can be used to measure the electro-magnetic parameters of the mushy and powdered materials. Moreover, the measured data of several kinds of material are given. According to the features of different measured objects, techniques for correcting some noticeable error factors are also discussed.

Key words: cascade network, decomposition, scattering parameter, mushy material, powdered material
