Researchers Develop New Lens for Terahertz Radiation

Terahertz radiation is a relatively unexplored slice of the electromagnetic spectrum, but it holds the promise of countless new imaging applications as well as wireless communication networks with extremely high bandwidth. The problem is that there are few off-the-shelf components available for manipulating terahertz waves. Now, researchers from Brown University’s School of Engineering have developed a new type of lens for focusing terahertz radiation (which spans from about 100 to 10,000 GHz). The lens, made from an array of stacked metal plates with spaces between them, performs as well or better than existing terahertz lenses, and the architecture used to build the device could set the stage for a range of other terahertz components that don’t currently exist. The work was led by Rajind Mendis, assistant professor of engineering (research) at Brown, who worked with Dan Mittleman, professor of engineering at Brown.

New Material Increases Lifetime of Solar-Powered Electrons

Nobody wants a laptop computer that stops working when a cloud passes by. Storing sunlight as fuel that can be later used to drive fuel cells requires new materials. Scientists demonstrated just such a material by combining two oxides on the atomic scale.

Force Sensors For Design

IN RECENT YEARS, factors such as consumer demand and a tough economy have pushed OEMs to produce sleeker, smaller, and less costly products than in the past. This forces designers to spec or engineer parts for increasingly tight space requirements. In this difficult situation, even small components such as force sensors can play a surprisingly big role in the development of successful solutions. A patented, thin-film, flexible but accurate force sensor was developed specifically to target industry needs for a low-cost, unobtrusive, force or pressure-measurement solution. The unique technology eliminates many of the challenges plaguing engineers in the design of streamlined products.

Managing Inherent and Environmental Thermal Effects On High-Power Laser Systems

A laser will only perform as designed if it emits the correct amount of power or energy and if the beam size is correct for the intended use. The same is true for high-powered lasers, however, the thermal effects that these lasers have on the system add a level of complexity to the application. Some thermal effects are inherent to the system as higher levels of light are applied to components within the system. Other thermal effects come from sources external to the system, such as debris produced from material processing.

Creating A New Category - Peelable FEP Heat Shrink Technology

Perhaps a controversial reference but relevant nevertheless, Machiavelli once noted that there is nothing more difficult “than to take the lead in the introduction of a new order of things”1 this certainly speaks to the challenge facing innovators as they create a “new category”, especially in a space that has been static for some time. Junkosha, a Japanese technology company, have a rich history of firsts, which have leveraged their core competencies in fluoropolymers and demanding wire and cable applications. This white paper outlines the experiences of one such first – Junflon Peelable FEP Heat Shrink.
