Measurement of Incremental Shottky Current in Dielectric Liquid

Temperature Tunability of Dielectric/ Liquid Crystal / Dielectric Photonic Crystal Structures

Recently, photonic crystals doped with liquid crystal (LC) material havegained much research interest. In this article new ternary one-dimensional photoniccrystal introduced and studied. The liquid crystal layer of 5CB and 5PCH is sandwichedby two dielectric layers. For the first time, we use four structures SiO2/UCF35/CaF2,SiO2/5CB/CaF2, NFK51/UCF35/NPSK53 and NFK51/5CB/NPSK53. The effect ofte...

Ultra sensitive measurement of dielectric current under pulsed stress conditions

Application of Pulse Method to Incremental Slitting Measurement of Residual Stresses in Laminated Composites

In this research, the incremental slitting method was employed to determine throughthickness residual stress profile of a carbon/epoxy laminate. The method involves measuring strains at the back surface of the stressed specimen, while a narrow slit is cut by a CNC milling machine progressively from the top surface of the specimen. "Pulse Method" was selected as the computational approach for th...

Adaptive dielectric liquid lens.

A tunable-focus liquid lens using dielectrophoretic effect is demonstrated. When a voltage is applied to a dielectric liquid droplet, the generated electric field inside the droplet is inhomogeneous. As a result, the liquid bears a dielectric force and its surface profile can be reshaped which causes the focal length to change. Adaptive lenses with different apertures are fabricated and their p...

Optical Measurement of Non-uniform Electric Field Vector Distribution in a Dielectric Liquid Using Triplet Measurement System

to identify the nature of the unstated approximations used in that work. The title clearly states that the subject of the paper is “optical measurements of non-uniform electric field” yet equations (1)-(9) are only valid for uniform electric fields whose direction is constant along the light path. These equations are presented as if they x e directly applicable to arbitrary non-uniform electric...
