ALMA Reveals Intense Magnetic Field Close To Supermassive Black Hole

The Atacama Large Millimeter/submillimeter Array (ALMA) has revealed an extremely powerful magnetic field, beyond anything previously detected in the core of a galaxy, very close to the event horizon of a supermassive black hole.

    A Clear Suit Of Armor For Your Smart Phone?

    Imagine a glass window that's tough like armor, a camera lens that doesn't get scratched in a sand storm, or a smart phone that doesn't break when dropped. Except it's not glass, it's a special ceramic called spinel {spin-ELL} that the U.S. Naval Research Laboratory (NRL) has been researching over the last 10 years.

    The Importance of GPS Derived Timing

    Many users of GPS believe its main function is to provide a means of deriving position, but the constellation of satellites is also a remarkably efficient time keeper. Each satellite contains 4 atomic clocks, so when their signals are received by any GPS enabled device, the synchronized time is within 100 billionths of a second, without the cost of owning, operating, and maintaining atomic clocks.

    Unmanned Aerial Vehicles: Growing Markets In A Changing World

    UAVs became a common part of many people’s vernacular due to their sudden surge in use for military related applications, though in those cases, they’re typically referred to as drones. Unmanned Aerial Vehicles have numerous potential civilian applications as well though – from agricultural, forestry, and maritime studies, to border security and law enforcement use. This article discusses the growing diversity of markets for UAVs and both the challenges and opportunities they provide.

Proving Installed Performance Of Airframe Microwave Assemblies

A recent study conducted for the aerospace industry showed that 29 percent of respondents said the cause of Microwave/RF cable failure or repair is due to damage during installation. Damaged airframe microwave assemblies result in system failures, re-testing, delayed production, increased maintenance downtime, and eventual replacement of the entire setup.

Overcoming Space Challenges And Reducing Costs With Small-Diameter Cable Technology

Network service providers are deploying more fiber cables than ever to keep up with bandwidth demands. While that’s good news for those who want more bandwidth, it’s not so good for the technicians needing access to existing circuits or the ability to install new ones. In order to help central offices, headends, and other areas of a service network, a microcable patchcord was developed to slow the rate of cable pile-up and ease congestion in fiber-management systems.

A Cost Effective Approach To Simulation For Electronic Warfare Systems

Electronic Warfare (EW) comes in the forms of Electronic Attack (EA), Electronic Protection (EP), and Electronic Support (ES). The tightening of the DOD’s budget has made the already complex simulation of the spectral environments encountered by EW systems in field settings even more of a challenge.

The Third Wave Of CFD: Paradigm Shift Towards Simulation-Driven Designs

This white paper covers the history of simulation flow through the first two waves of CFD (computational fluid dynamics) technology, from the beginnings of commercially available CFD software through its entering of R&D departments. Lastly, it outlines the paradigm shift occurring in CFD technology as it has now become an essential element of the product design process as simulation-driven design is more prominent now than ever.

    4 Electronic Design Requirements Of The System-Integrated Soldier

    Perhaps most famously portrayed in Robert Heinlein’s Starship Troopers (1959), the idea of the “future soldier” has been around for decades. As rehashed in countless science fiction films and video games, the stereotypical future soldier is equipped with a protective exoskeleton, enhanced sensory equipment, seamless communication systems, and advanced weaponry. While the concept once seemed implausible, there are many real-world projects under way focused on realizing those seemingly fictitious warfighter capabilities — by integrating a plethora of diverse electronic subsystems into a cohesively operational suit.

    7 Noteworthy Technologies From IMS2014

    At the 2014 IEEE MTT International Microwave Symposium earlier this month, I had the opportunity to speak with the event’s general chair, Dr. Larry Dunleavy, about the state of the RF and microwave design industry. While he acknowledged that it is a time of relative uncertainty — due in large part to constrained military budgets and conservative fiscal forecasts for 2014 — he also pointed out that there are plenty of emerging markets where RF and microwave technology is making a significant impact. With the Internet of Things (IoT) driving innovation in burgeoning markets like automotive and healthcare  and the development of 5G pushing wireless technology to further heights, there was good reason for nearly 600 companies to flock to the IMS2014 exhibition in Tampa, Fla.
