An adaptive microlens structure is proposed using two polymer-stabilized blue-phase liquid-crystal layers whose Kerr constant is largely mismatched. This device exhibits several favorable features, such as polarization independence, simple structure, and good parabolic phase profile. Its applications for 2D/3D switchable displays and other photonic devices are emphasized.

We examine the photo-assisted polarization loop in a BiFeO3 thin film under UV light illumination. BiFeO3 thin film prepared by pulsed laser deposition method onto the BaTiO3 thin film and the polarization behavior has been measured under poling voltage. Our results show the engineered polarization due to controllable schottky barrier under inverse poling voltage. This control on schottky barri...

The dynamics of pseudo-classical spinning particles in spacetime of gravitational plane waves of general polarization and harmonic profile is studied. The resulting equations of motion are solved exactly and the results are compared with those of the other approaches. The relative accelerations of nearby particles is also calculated.

We propose a new microlens device structure using two polymerstabilized blue phase liquid crystal layers whose Kerr constant is largely different. Such a polarization independent microlens has a simple structure and desired parabolic phase profile. Its applications for 2D/3D switchable displays and other photonic devices are emphasized.

We report the design and simulation results of an adaptive GRIN lens based on multi-electrode addressed blue phase liquid crystal. A high dielectric constant layer helps to smoothen out the horizontal electric field and reduce the operating voltage. Such a GRIN lens is insensitive to polarization while keeping parabolic phase profile as the focal length changes.

In this paper, we assess potentials and limitations of vertical structure estimation via polarization coherence tomography (PCT) for the processing of multibaseline SAR data, by using simulated data. We discuss the quality of the profile retrieval for natural environment in presence of several distortions as system errors and inaccurate a priori information, by means of simulations.

Dual-band antenna elements that support dual-polarization provide ideal performance for applications including space-based platforms, multifunction radar, wireless communications, and personal electronic devices. In many communications and radar applications, a dual-band, dual-polarization antenna array becomes a requirement in order to produce an electronically steerable, directional beam capa...

Polarization sensing is one of the important optical measurement scheme used in various scientific and industrial applications. For instance, an optical rotation measurement is widely used to measure chirality of chemical species. The polarization of light is modulated when the light propagates the optically active material such as saccharide or protein. Polarization rotation reflects concentra...

Polarization in the Lyman-α line caused by anisotropic electron collisions has been investigated Large Helical Device (LHD).
