The Analysis and Measurement for Three-port Scatter Parameters of Substructure in Multimode Feed Network
نویسندگان
چکیده
In opinion of substructure cascade, multimode feed network is composed of impedance transforming substructure and isolating substructure. Starting from the characteristic of the substructure in multimode feed network, a method of measurement for its three-port scatter parameters of substructure is presented, based on the applying of the available two-port vector network analyzer (VNA), considering the port impedance matching, the three-port scatter parameters of substructure in multimode feed network are researched, the mixed-mode Sparameters of three-port networks are used to verify the actual measured data. All those provide a favorable base for the optimizing design of the entire multimode multi-feed antenna system. Copyright © 2013 IFSA.

Calculation of the Scattered Radiation Profile in 64 Slice CT Scanners Using Experimental Measurement
Introduction: One of the most important parameters in x-ray CT imaging is the noise induced by detected scattered radiation. The detected scattered radiation is completely dependent on the scanner geometry as well as size, shape and material of the scanned object. The magnitude and spatial distribution of the scattered radiation in x-ray CT should be quantified for development of robust scatter...
