Double-Sided Design of Electrodes Driving Tunable Dielectrophoretic Miniature Lens

Design Optimization and Construction of Double-Sided Linear Induction Motor

Linear induction motors have single and double-sided structures which are used in special applications, according to their advantages and disadvantages. Due to advantages such as lack of normal forces in double-sided type, these motors are more controllable and popular than the single-sided type, especially for transportation applications.  In literature, single-sided linear induction motors ha...

Optimum design of a double-sided permanent magnet linear synchronous motor to minimize the detent force

In the permanent magnet linear synchronous motor (PMLSM), force ripple is harmful, useless and disturbing. The force ripple is basically composed of two components: detent force and mutual force ripple. This force is influenced by the geometric parameters of the permanent magnet (PM) motors; such as width, thickness and length of the magnet poles, length and thickness of the rotor and stato...

Near-Diffraction-Limited Tunable Liquid Crystal Lens with Simplified Design

Tunable polymer lens.

A new type of solid-state variable focal length lens is described. It is based on shape changes in an elastomeric membrane driven by compression of a reservoir of a polymer gel. A novel fabrication process based on individual lens components allows for customization of lens power based on the desired application. The lens shape as a function of applied compressive strain is measured using direc...
