State-transition-matrix method for inverse scattering in one-dimensional inhomogeneous media.

摘要: This study presents an analytical approach for the electromagnetic characterization of one-dimensional inhomogeneous media. The proposed provides permittivity profile medium in terms reflection and transmission coefficients. inverse solution is obtained with help state-transition matrix (STM) its properties, which are presented proved. advantage using this analytic reconstruction technique ability to remove complexity nonlinearity problem. Several examples have been considered validation and, each case, quite good agreement has found between original reconstructed profiles. It established from results that when scattering parameters combined properties STM, a robust reliable provided
