In spite of the fact that there are different techniques in the creation of the high-quality liquid crystals (LCs) alignment by means of various surfaces, the azimuthal and polar anchoring energies as well as the pre-tilt angle are important parameters to all of them. Here, the modified by...
It is shown that simultaneous control of both polar and azimuthal orientation of liquid crystal is possible using the chemical nanopatterns as alignment layer. While the liquid crystal azimuthal angle orients along the direction of the silane lines, the polar orientation depends on the coverage ...
Define Azimuthal angle. Azimuthal angle synonyms, Azimuthal angle pronunciation, Azimuthal angle translation, English dictionary definition of Azimuthal angle. n. 1. The horizontal angular distance from a reference direction, usually the northern point o
Direction of the light source specified as [a azimuthal angle, p polar angle] where a indicates the azimuthal angle of the light relative to north (in degrees and proceeding clockwise), and p indicates polar angle of the light (from 0 degree, directly above, to 180 degree, directly below)...

(1.1) with θi the polar angle between the momentum of the decay product i = +, ν, d¯, u, b, W + in the rest frame of the parent top quark, and some reference axis sˆt; P is the top polarisation along that axis, and αi are constants that, because of angular momentum...
When the CERES operates in the RAPS mode, the cloud information and radiances come from two different viewing perspectives. The VIRS scanning angle limits the angular coverage by the SSF, so that some CERES RAPS data with VZA between 48° and 70° are not used because they have no matching...
is the azimuthal angle between the vertical plane and the fracture direction. Therefore, in HTI media, in order to analyse and compensate for the azimuthal variation of the PS converted wave recorded in the radial component, it is essential to consider the P-SV1 and P-SV2 waves separat...
