Laser, a device that stimulates atoms or molecules to emit light at particular wavelengths and amplifies that light, typically producing a very narrow beam of radiation. The emission generally covers an extremely limited range of visible, infrared, or ultraviolet wavelengths. Many different types of lasers have been developed, with highly …

An antenna is a device used to propagate, receive, and/or transmit electromagnetic waves which can have information embedded within them. The antenna creates an electromagnetic wave that carries the original embedded sound information through the atmosphere/space around it. An antenna at a different location, receives the electromagnetic wave, sending it …
Read More »Virtual Reality (VR) is the use of computer technology to create a simulated environment that can be similar to or completely different from the real world. Unlike traditional user interfaces like viewing a screen in front of them, users are immersed and able to interact with 3D worlds. Applications of …

Millimeter waves are electromagnetic signals with frequencies ranging from 30 to 300 GHz that correspond to wavelengths of 10 to 1 mm in the free space. Electromagnetic waves in the millimeter-wave band (with frequencies between 30 and 300 GHz, or wavelengths between 10 and 1.0 mm) have attractive characteristics. One of …

Time to market demand has forced integrated circuit design, manufacturing and testing to be done at different places across globe. This approach has led to numerous security concerns like overbuilding of chips from foundries, IP protection, counterfeiting and hardware Trojans. Hardware Trojans (HT), which are malicious circuit inclusions into the …

DARPA, is proposing a new Mosaic Warfare strategy for evolving multidomain battlefield. Dr. Timothy Grayson, Director of the Strategic Technology Office is advocating for a “system of systems” approach that he’s calling mosaic warfare: the ability to piece together different systems to build new overarching warfighting capabilities. DARPA’s Strategic Technology …

We see things because our eyes are sophisticated light detectors: they constantly capture the light rays bouncing off nearby objects so our brain can construct an ever-changing impression of the world around us. Similarly in a camera, All the light traveling from the object enters a single lens before it …

Broadband fiber-optics carry information on pulses of light, at the speed of light, through optical fibers. But the way the light is encoded at one end and processed at the other affects data speeds. Basically, light or any other electromagnetic radiation has energy defined by its frequency and momentum defined by …

Space-division multiplexing (SDM) has recently attracted great attention as a promising technology to further improve the transmission capacity and spectral efficiency. Very recently, SDM employing twisted lights, also known as orbital angular momentum (OAM) carrying lights, provides an alternative approach to increasing the transmission capacity and spectral efficiency of optical communications. …

As the world continues to change and advance at a rapid pace, the need for continuous innovation has never been greater. DARPA’s open innovation model leverages the expertise and novel ideation found in large and small businesses, government organizations, and academic institutions. However, resource constraints across these organizations can limit …
