Reconfigurable metamaterial structure for 5G beam tilting antenna applications [PDF]

, 2020
In this paper, we propose a metamaterial (MTM) structure with a reconfigurable property designed to operate at the millimetre-wave (mm-wave) spectrum. Four switches are used to achieve the reconfigurable property of the MTM with two configurations. These

Photoresponsive Passive Micromixers Based on Spiropyran Size‐Tunable Hydrogels

Macromolecular Rapid Communications, 2017
AbstractMicrofluidic devices allow the manipulation of fluids down to the micrometer scale and are receiving a lot of attention for applications where low volumes and high throughputs are required. In these micro channels, laminar flow usually dominates, which requires long residence times of the fluids, limiting the flow speed and throughput.

A fast passive and planar liquid sample micromixer

Lab Chip, 2004
A novel microdevice for passively mixing liquid samples based on surface tension and a geometrical mixing chamber is presented. Due to the laminar flow regime on the microscale, mixing becomes difficult if not impossible. We present a micromixer where a constantly changing time dependent flow pattern inside a two sample liquid plug is created as the ...

Numerical and Experimental Study of Mixing Characteristics in a Spiral Micromixer

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Significant enhancement of mixing performance can be achieved by Dean vortices in spiral channels. In order to deeply explore the mixing mechanisms and variation laws in spiral micromixers, this work designed a spiral micromixer and adopted a combined method of experiments and numerical simulations to analyze the mixing performance and ...
