Determination of the electromagnetic wave polarization from unknown sources by the method of linear component modified

Abstract

In this paper, we propose a modification of the linear component technique for identification of the electromagnetic waves polarization. The proposed measurement is divided in two setups and is used to obtain the amplitude of the two accessible electric field components of a plane wave. From the axial ratio and the discrete phase information obtained by trial, it is possible to determine the amplitude and phase of the electric field radiated by one or more sources. The setup is constituted by a pair of dipoles orthogonally positioned to determine these two field components. The results are obtained for two kinds of polarization: linear and circular. Good agreement was obtained between the simulated and measured results.
