As to scalar measurement systems with the joint Tx/Rx polarization optimization, we provide numerical examples to demonstrate the effectiveness of the devised algorithms, in comparison with two other polarization approaches.
According to our observations of behavior of spherical magnets, the magnets create clusters with less energy in which vectors of polarization subtract one another and final vector of polarization approaches to zero.
Between the wavelengths λ = 1.49 μm and λ = 1.52 μm, the degree of circular polarization approaches unity (> 90%) for both states, confirming the most appropriate operation region of the structure as a QWP. Figure 8a, b shows the phase distribution of the z component of the electric field, calculated at the design wavelength λ = 1.5 μm at z = 0.
(2) A tilt-like surface deformation to achieve a uniform phase distribution in reflector aperture for circularly polarized offset cable mesh reflector antennas is provided in the optimal structural design, and the electromagnetic performance including boresight directivity, beam squint angle, sidelobe levels and cross-polarization approaches better as the phase distribution becomes uniform.

The imaging technique was investigated with a polarization contrast approach to acquire high-contrast images.
We further present polarization engineering approaches to enhance p-type doping, including Mg-doped superlattices, distributed polarization doping, and tunnel-junction-enabled LEDs.
Consequently, the present polarization modulation approaches can be easily extended to analogous measurements performed with high numerical aperture objectives.
The reported C polarization level approaching unity (>15.6%), long lifetime of C hyperpolarized 1-C-phospholactate d2 (58 ± 4 s versus 36 ± 2 s for nondeuterated form at 47.5 mT), and large production quantities (52 μmoles in 3 mL) in aqueous medium make this compound useful as a potential contrast agent for the molecular imaging of metabolism and other applications.
