polarization
In the interesting case when the group is of Coxeter typeDn (n≥4) we use higher polarization operators introduced by Wallach.
      
When the characteristic of k is 0, it is known that the invariants of d vectors, d ≥ n, are obtained from those of n vectors by polarization.
      
From elements of the invariant algebra C[V]G we obtain, by polarization, elements of C[kV]G, where k ≥ 1 and kV denotes the direct sum of k copies of V.
      
The remanent polarization (Pr) and coercive electric field (Ec) of the measured PZT thin films are 47.7 μC/cm2 and 18 kV/cm, respectively.
      
Impact of polarization mode dispersion and nonlinear effect on 40 Gbit/s dense wavelength division multiplexing system
      
However, the fiber nonlinear effects and polarization mode dispersion severely limit the performance of the system when signal propagates at 40 Gbit/s in a single channel.
      
The insertion loss (IL) is 3.40 dB, the polarization dependent loss is 0.47 dB, the extinction ratio (ER) at bar state and cross state is 32.01 dB and 16.42 dB respectively, the response time is less than 3 ms, and the power consumption is 658 mW.
      
A novel broadband and high-gain microstrip reflectarray antenna with variable polarization
      
This article proposes a new kind of microstrip reflectarray antenna, of which the polarization could be reconfigured among all the polarization states instead of some fixed states in a dual-or multi-polarized antenna.
      
Theoretical analysis shows that the reflected polarization covers all states and that the dual-or multi-layered unit structure sandwiched with air-gaps can broaden the bandwidth efficiently.
      
The kurtosis (K) of the two forests (one was -0.64, the other was -0.74) had little distinction and the density factor had limited function to forest polarization.
      
Influence of local spin polarization to the Kondo effect
      
We use the spin non-degenerate single impurity Anderson model to investigate the influence of the local spin polarization to the Kondo effect.
      
The local spin polarization generates the instability of the singlet ground state of the S = 1/2 s-d exchange model.
      
Gradient-stress on polarization in Ba1-xSrxTiO3 films
      
The dependence of the effective dielectric constant on the temperature and the average spontaneous polarization on the film thickness are computed, which qualitatively agree with the experiments.
      
An arbitrary Greenberger-Horne-Zeilinger state can be discriminated using two-photon polarization parity detection which resorts to cross-Kerr nonlinearity between a single-photon qubit and probe field.
      
Their performance was tested by cyclic voltammetry and potentiostatic polarization by utilizing their inherent powder microelectrode in 0.5 mol/L CH3OH and 0.5 mol/LH2SO4 solution.
      
Meanwhile, the tetragonality of the perovskite phase is increased when Pb2+ ions increase due to its high polarization.
      
The polarization reversal characteristics were measured, and the typical piezoelectric hysteresis loop was recorded.
