Venus Revealed In Radio Light

From earthbound optical telescopes, the surface of Venus is shrouded beneath thick clouds made mostly of carbon dioxide. To penetrate this veil, probes like NASA’s Magellan spacecraft use radar to reveal remarkable features of this planet, like mountains, craters, and volcanoes.

    Knowing Where To Go In Virtual Worlds!

    Virtual reality (VR) makes it possible to immerse oneself in new and unfamiliar computer worlds. This technology features strengths that industrial companies, architects and city planners are finding increasingly important for their planning and training processes.

  • NRL Researchers Pattern Magnetic Graphene
    NRL Researchers Pattern Magnetic Graphene

    Graphene, an atomically thin sheet of carbon, has been intensively studied for the last decade to reveal exceptional mechanical, electrical, and optical properties. Recently, researchers have started to explore an even more surprising property—magnetism.

  • Unified Theory For Skyrmion-Materials
    Unified Theory For Skyrmion-Materials

    Magnetic vortex structures, so-called skyrmions, could in future store and process information very efficiently. They could also be the basis for high-frequency components. For the first time, a team of physicists succeeded in characterizing the electromagnetic properties of insulating, semiconducting and conducting skyrmion-materials and developed a unified theoretical description of their behavior. This lays the foundation for future electronic components with purpose-designed properties.

    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, and 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.

The Unique Requirements For Wireless Medical Devices

Medical device designers and manufacturers who don’t understand the unique requirements for ensuring success in a WLAN (wireless local area network) deployed solution run the risk of their device having adverse performance, potential regulatory recalls, the need for a product re-design, revenue loss, and competitive market positioning.  

The Basics Of Quadrifilar Helix Antennas

With the explosive growth of satellite-based services, the ability to receive or transmit a tight beam of circularly polarized radiation while minimizing unwanted radiation is imperative to maintaining good communication.  For such demanding applications, the axial-mode quadrifilar helical antenna provides a high performance and robust antenna platform both in space as well as on the ground.  Furthermore, for portable and handheld radio systems,  the quadrifilar helical antenna can be readily miniaturized, providing good quality circular polarization and near hemispherical coverage in the UHF and microwave bands.

    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.
