Completely polarized electromagnetic wave measurement by linear component method

Abstract

In this paper, we propose a refinement of the linear component technique in identifying the polarization of electromagnetic waves. The waves propagate in free space and are considered completely polarized. 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.
