The present article deals with the analysis of thermal-bending stresses in a heated thin annular sector plate with simply supported boundary condition under transient temperature distribution using Berger’s approximate methods. The sectional heat supply is on the top face of the plate whereas the bottom face is kept at zero temperature. In this study, the solution of heat conduction is obtained...

We introduce the concept of Shannon dimensionality D as a new way to quantify bipartite entanglement as measured in an experiment. This is applied to orbital-angular-momentum entanglement of two photons, using two state analyzers composed of a rotatable angular-sector phase plate that is lens coupled to a single-mode fiber. We can deduce the value of D directly from the observed two-photon coin...

A laser beam with mixed linear-radial polarization formed by reflection of a linearly polarized light from a 4-sector micropolarizer was focused using a binary zone plate in a focal spot with diameters 0.35±0.02 and 0.38±0.02 of a wavelength.

• A sector-based Fresnel Zone Plate with Extended Depth of Focus is proposed. Easy to manufacture since the proposed plate binary. Potential applications in many technological areas. An increasing almost 7 times less than double width focus obtained. Sector-based zone consists a binary diffractive lens composed mosaic sectors plates different focal distances. When these distances are linearly d...

Analytical solutions for elastic buckling and post-buckling geometries are scarce. The present work presents such a solution sample geometry, initially planar, which buckles into complex 3D shape under tensile load. assumptions that the thickness is small, so flexural stiffness low compared to in-plane strain stiffness, hence can be considered inextensible. initial geometry composed of two disk...

This paper presents design of an alternating-phase fed single-layer slotted waveguide array for a sector shaped beam in the Eplane radiation pattern. A sector beam pattern is very effective for radar applications for detecting obstacles in a certain angular range without mechanical or electronic scanning. The sector shaped beam with 13 degree beam width is synthesized by a cascade of T-junction...

abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...
