Introduction: In recent years, metasurfaces have been demonstrated to control the phase and amplitude of light across a planar interface and implemented for optical functions such as beam-steering, focusing, and polarization rotation. Initial efforts using plasmonic-based scatterers ... En savoir plus
Utility-scale photovoltaic (PV) and concentrated solar power (CSP) generation facilities are located in desert environments throughout the world to take advantage of the high availability of sunlight in these areas. Unfortunately, naturally occurring sandstorms in these deserts often ... En savoir plus
Electrochemical machining (ECM) is a manufacturing technology that allows metal to be precisely removed by electrochemical oxidation and dissolution into an electrolyte solution. ECM is suited for machining parts fabricated from “difficult to cut” materials and/or parts with complicated ... En savoir plus
Laminar forced convection is studied in a vertical rectangular channel with seven discrete heat sources and dummy heat sources mounted on a wall. The position of seven heat sources is fixed in an optimal arrangement. The heat transfer effects are investigated by numerical simulation and ... En savoir plus
Engineering design has long been dominated by orthogonal Cartesian principles. Nature inspired equation based mathematical surfaces are under renewed interest due to their innovative design potential and practical viability by 3D printing. In this paper, the parametric surface ... En savoir plus
With the advancements in aerospace technology, micro-electromechanical systems, hybrid data centres and microfluidics, the miniature size electronic chips in such applications are need of the century.

Introduction: Flat lenses require precise control of a phase gradient across an interface, which is enabled through the application of engineered surfaces, such as Metasurfaces [1]. Periodic arrays of plasmonic antennas have been utilized to generate this desired phase gradient, which ... En savoir plus
Optimization of a typical electrochemical system with insulating shields is considered in this work, which objective is to reduce the current peak due to singularity and smooth the current density distribution along electrode surface. Moving mesh method was adopted to allow change in ... En savoir plus
We develop a porosity-optimization problem to improve the electrochemical reactions taking place in hydrogen fuel cells. We introduce a mathematical model, which involves a system of conservation laws defined in a porous space domain. Our goal is to find the domain's optimal porosity ... En savoir plus
