Electromagnetic scattering from radially inhomogeneous cylindrical structures using the state space method

In this paper, the state space method is developed for analysis of the scattering of radially inhomogeneous cylindrical structures. The developed technique is based on obtaining and using the state transition matrix of cylindrical layers. The most valuable and interesting property of the presented method is its systematic approach, allowing one to easily apply this method to any types of cylindrical inhomogeneous media and simply implement it in a programming language supporting matrix manipulations. The validity of the presented method as well as the correctness of the formulation is achieved by providing some numerical examples and comparing the obtained results with the results of previously published works.
