Electrokinetically tunable optofluidic bi-concave lens
This paper numerically and experimentally investigates and demonstrates the design of an optofluidic in -plane bi-concave lens to perform both light focusing and diverging using the combined effect of pressure driven flow and electroosmosis. The concave lens is formed in a rectangular chamber with liquid core liquid cladding (L) configuration. Under constant flowrates, the performance of the le...

متن کاملPlane Wave Propagation Through a Planer Slab
An approximation technique is considered for computing transmission and reflection coefficients for propagation of an elastic pulse through a planar slab of finite width. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is s...
متن کاملPLANE WAVE PROPAGATION THROUGH A PLANER SLAB
An approximation technique is considered for computing transmission and reflection coefficients for plane waves propagating through stratified slabs. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is shown that it depends ...
متن کاملFocusing concave lens using photonic crystals with magnetic materials.
The guided modes lying in the upper gap-edge band in the photonic band structure of photonic crystals have negative values of refractive index. This feature generates many interesting optical phenomena, and some spectacular photonic devices such as focusing slabs have been developed. We report the design of a photonic-crystal, planoconcave lens for focusing incident parallel light, and theoreti...
