Effective Electromagnetic Properties of Lossy Ferrite Composite Media.

摘要

This report discusses both the theoretical and experimental aspects of the problem of defining effective electromagnetic properties of non-homogeneous media. A simple theory has been developed for a one-dimensionally periodic medium containing lossy ferrite strips and the theory has been experimentally verified. This theory has been extended to two-dimensionally periodic media. An empirical theory has been applied to a composite medium composed of a honeycomb structure loaded with a lossy ferrite and experimentally verified. A computer program has been presented which is useful in solving the problem of one-dimensionally periodic media. The project is part of an ongoing program to develop new and efficient radar absorber materials. (Author)
