Time-frequency distributions (TFDs) have evolved to be a powerful technique for nonstationary signal analysis and synthesis. With the use of a multi-sensor array, spatial time-frequency distributions (STFDs) have been developed and successfully applied to high-resolution direction-of-arrival (DOA) estimation and blind recovery of the source waveforms. In this paper, the polarimetric dimension i...

This paper presents the results achieved with a dualpolarized multiple-input multiple-output (MIMO) measurement system in the 2 GHz range. Results from continuous measurement routes were used in evaluating and comparing different MIMO antenna configurations. Different pattern and polarization diversity possibilities were studied using two methods: elements were selected from the antenna arrays ...

Spin dependent fragmentation functions for heavy flavor quarks to fragment into heavy baryons are calculated in a quark-diquark model. The production of intermediate spin 1/2 and 3/2 excited states is explicity included. Λb , Λc and Ξc production rate and polarization at LEP energies are calculated and, where possible, compared with experiment. A different approach, also relying on a heavy quar...

In this study, groups who could not reach a consensus were investigated using the group polarization paradigm. The purpose was to explore the conditions leading to intragroup disagreement and attitude change following disagreement among 269 participants. Analysis indicated that the probability of consensus was low when the group means differed from the grand mean of the entire sample. When smal...

We present a linear Stokes polarization camera working at visible wavelength. The camera is both compact and robust for use in field experiments and outdoor conditions. It is based on fast polarization modulator. Four polarization states images are acquired successively. Processing software allows live calculation, visualization and measurement of polarization images deduced from the acquired i...

The separation of the absorption of linearly polarized resonant radiation by anharmonic local vibrations of cubic symmetry is analyzed by the method of the quantum kinetic equation. It is shown that as a result of the symmetry-induced degeneracy of the energy levels the absorption saturation is accompanied by rotation of the radiation polarization towards one of the symmetry axes of the crystal...

The spectral shift amplification effect and polarization-controlled spectral shifts are studied using silver (Ag) metal. The spectral shift amplification factor can be doubled by using silver compared with using water. The solid Ag metal surface also provides orientation freedom for polarization-controlled spectral shifts, benefiting data transmission applications in any direction. The liquid w...

Diversely polarized antenna arrays are widely used in RF applications. The diverrity of rerponse provided b y such arrays can greatly improve direction finding performance over arrays sensitive to only one polarixation component. For d emitterr, direct implementation of a multidimensional estimation algorithm (e.g., maximum likelihood) requires a search f o r 3d parameters: d directions of arri...

Free rotating impurity-vacancy (IV) dipoles in an alkali halide matrix are polarized to the extent of 1/3 of the total number of IV dipoles. An experimental procedure is suggested in this article which will help in the polarization of IV dipoles to the extent of 2/3 of the total number of IV dipoles. In the suggested experimental procedure, the electric field will be applied at first in one dir...

We show that for an observer in translational, rotational or gravitational motion, a linearly polarized plane wave has two modes of propagation in a stationary, homogeneous and isotropic medium according to Hertz’s version of Maxwell’s theory. The first mode is characterized by polarization at right angles to the direction of propagation and has a phase velocity that is controlled by the materi...
