Polarization of dielectric material is performed under action on it of electric field and acoustic oscillations with frequency equal to resonance frequency of longitudinal oscillations of this material with the help of dielectric spacer placed between source of acoustic oscillations and material.

A computationally simple yet powerful method for distinguishing metal and dielectric material surfaces from the polarization characteristics of specularly reflected light is introduced. The method is completely passive, requiring only the sensing of transmitted radiance of reflected light through a polarizing...
An ambichiral structure comprising sheets of an anisotropic dielectric material rejects normally incident plane waves of one circular polarization (CP) state but not of the other CP state, in its fundamental Bragg regime. However, if the same structure is made of an dielectric--magnetic material ...
for lenses and prisms), while others are used as dielectric coatings, usually having a quite small thickness. There are also cases where one starts with a dielectric bulk material and locally modifies that to obtain a waveguide, or structures it to obtain a diffraction grating. Further, some ...
The use of a liquid dielectric material in the energy-loss return gate generates electrostatic potential energy while reducing the dielectric loss of the electric/electronic system. Hence, an energy-loss return gate can make breakthrough impacts possible by amplifying energy-harvesting efficiency, ...
We report on the mechanism of the dielectric properties of oxygen vacancy in ZnO, using ab initio numerical simulations of oxygen vacancy on the band structure and dielectric properties, to develop photoelectric material applications. It is revealed that the appearance of oxygen vacancies leads to wid...
Metasurfaces are capable of tailoring the amplitude, phase, and polarization of incident light to design various polarization devices. Here, we propose a metasurface based on the novel dielectric material gallium nitride (GaN) to realize high-efficiency modulation for both of the orthogonal linear pol...
The force interaction is greatly enhanced by securing a high dielectric material adjacent to each mirror. Thus forces and torques are produced without the use of motors. This allows maximization of solar energy focused by a low-profile concentrator array onto a receiver. Dynamic motion can be ...
A new polarization-independent unit cell design was developed for all-dielectric metasurfaces that can be CMOS compatible. This new design can achieve beam steering with the highest efficiency to date of 0.89 for x-polarized field and 0.81 for y-polarized light. This design can be tailored to ...
