Polarization Degrees of Freedom of Hexapolarized MIMO System in the Ground Reflected Channel
IEICE Transactions on Communications, 2011The polarization degrees of freedom (DOF) of the hexapolarized multiple input multiple output (MIMO) system over the ground reflected channel is studied in this paper by the deterministic field solution. Using the simple two-ray model, we could get some basic understandings for the influence of a single reflecting surface on the polarization DOF of the

On the Number of Degrees of Freedom in Dual-Polarized GNSS Adaptive Arrays
2018 18th International Symposium on Antenna Technology and Applied Electromagnetics (ANTEM), 2018It is known that a dual-polarized adaptive array with N elements has a maximum of 2N-1 degrees of freedom for beamforming. For small global navigation satellite system (GNSS) adaptive arrays, we show that this maximum can be easily achieved if the interferer polarizations are random.

On the degrees of freedom in linear array systems with tri-polarized antennas
IEEE Transactions on Wireless Communications, 2008In this paper, we provide a theoretical, simulation and experimental characterization of the performance of linear arrays of tri-polarized dipole antennas in multiple input multiple output (MIMO) systems in terms of degrees of freedom and channel capacity.

We demonstrate two entanglement concentration protocols (ECPs) for photon pairs in less-hyperentanglement, the simultaneous entanglement in multiple degrees of freedom. Using these ECPs, some maximally entangled states in polarization can be reconstructed deterministically from less-hyperentangled ones shared between remote participants.

Quantum delayed-choice protocol by means of the polarization degree of freedom of a photon
Journal of the Optical Society of America B, 2018In this work, we revisit the previously demonstrated experiment called the quantum delayed-choice experiment [Phys. Rev. Lett.107, 230406 (2011)PRLTAO0031-900710.1103/PhysRevLett.107.230406], which shows that it is possible to reveal the wave and particle nature of photons simultaneously.
