    Electromagnetics In The Healthcare Industry

    Electromagnetic (EM) fields are present in many of the medical applications today. The technology is becoming more complex, and it is therefore vitally important that the tools and procedures perform at their maximum capacity and always yield precise and accurate data.

The Rx For 5G RF

The mobility and Internet of Things explosion has led to a severe wireless spectrum shortage, driving researchers to seek new ways to alleviate the bandwidth crunch. Wireless researchers now anticipate 5G to arrive at the end of the decade, providing a 1000x increase in network capacity. In this article, Moor Insights & Strategy provides information on major areas of 5G research, describes current challenges in wireless design, and introduces new design tools from NI geared for helping RF design engineers.

Reducing Life Cycle Costs With Reliable Airframe Microwave Assemblies

In this white paper, W. L. Gore & Associates evaluated the performance of microwave airframe assemblies before and after installation. This testing showed that the performance of many assemblies degrades significantly because they get damaged during installation, which results in increased costs, production delays, and additional testing to requalify system components. Selecting a durable cable assembly that has been tested to survive challenging aerospace applications is the key to reducing costs and ensuring reliability over time.

    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.

    EM De-Embedding Magic – Part 2: Lots Of Ports, All Talking To Each Other!

    In part I, I described how I came up with the EM port calibration theory that we have been using very successfully for nearly 30 years. It is so simple. To de-embed a single, lonely port, just EM analyze a 2-port through line of length L, and a second one of length 2L, do some magic math (described in Part I and in [1] and [2]), and we have beautiful, fully de-embedded EM analysis data for that lonely port. (If we have additional lonely ports, just repeat the process for those ports, one at a time, as well.)
