Abstract: This research focuses on the design, fabrication and testing of a compact, flexible 4-element array using Aerosol jet printing technology (AJP). The array operates at ISM-band 2.45 GHz for ...

Abstract: A novel and accuracy phased array calibration method is presented in this paper. The method improves the rotating-element electric-field vector (REV) method, where the phase of each element ...

Tungsten carbide–cobalt (WC–Co) is prized for its hardness, but that same property makes it unusually difficult to shape. The current process is wasteful and expensive for the yield produced, and an ...

3D printing may be a breakthrough technology, but it isn’t sustainable. Most printers still rely on petroleum-based plastics, while greener alternatives are too brittle to use in parts that need ...

Every breath you take, they really may be watching you. By Veronique Greenwood Your thumbprint, the pattern of lines in the iris of your eye: These are known to be more or less unique to each person, ...

Exhibition coordinator Ellen Mensch says she learns something new every time the National Print Exhibition comes around at Artlink. “What’s most interesting to me about this show in particular is it ...

In this paper, the optimal control problem of parabolic integro-differential equations is solved by gradient recovery based two-grid finite element method. Piecewise linear functions are used to ...
