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.

IoT Drives Demand for Automotive Circuit Protection Solutions

In the past, automobiles were made up of many independent electronic systems. Even the assembly lines that were used to manufacture the vehicles required the operation and management of multiple independent systems. However, the advent of the Internet of Things (IoT) has changed automotive electronics and assembly dramatically. The connectivity that used to only be available in the home or office is now available in modern automobiles. The car itself has now become the center of communication.

Software Helps Restore Fire-Ravaged Habitats

NASA system uses the cloud to give land managers and wildlife experts a post-fire plan. The Department of the Interior’s Bureau of Land Management (BLM), in addition to coordinating firefighting efforts on federally held lands, is also responsible for the post-fire restoration process that’s meant to limit the harmful fallout.
