The 2016 Presidential election features a wide range of Republican contenders. How do they compare to John Charles Fremont, who in 1856 became the very first Republican candidate for President? Adventurer, explorer, military officer, businessman, and U.S. Senator, the current contenders must pool their experience to match Fremont’s remarkable resume. […]

How Do Today’s Republican Candidates Compare to the Very First?


Famed explorer and adventurer John Charles Fremont was born on this day, 203 years ago in 1813. In honor of the occasion, my book, The Biographies of John Charles Fremont, is now available in a Kindle edition from Amazon for free through the weekend (Sunday January 24). As always, the […]

Circuit Physics Models
My work explores the practical aspects of how bound, stored, or static electromagnetic energy transforms into moving electromagnetic energy. I’ve applied this expertise in the design of ultra-wideband (UWB) antennas, as well as in wireless systems that operate using near-field wireless principles. Q-Track designs indoor location systems that locate tags […]

One great challenge in parenting is finding worthwhile educational videos. My kids prefer the zany antics of Phineas and Ferb to most anything with a wiff of being educational. That’s why I’m delighted to have found a great series that combines education with engaging entertainment for the whole family. How […]

Napoleons Buttons 1
Napoleon’s Buttons is not a history of chemistry but rather the story of how chemistry influenced history. Seventeen chapters detail how chemicals have played a crucial role in human development from ancient times to the present. A sampling of topics include: Spices and their role in trade, Ascorbic acid, scurvy […]

Two slit interference of waves.
The folks at Loughborough University in the UK have developed and released a fascinating educational application to illustrate the behavior of waves. The Loughborough Wave App offers an intuitive interface to allow the user to explore a variety of simple wave phenomena. This is not an analytic tool. Rather it’s […]

One of the great pleasures of having written a book is hearing feedback from readers. I’m particularly interested in readers who have applied ultrawideband antenna ideas and concepts to solve problems with which I was completely unfamiliar. Martin Judd of High Frequency Diagnostics in Glasgow, Scotland has graciously agreed to […]

SafeSpot protects workers by warning of potential accidents before they happen.
SafeSpot™ systems make busy workplaces safer by warning pedestrians and forklift drivers of potential collisions. The system triggers a warning around blind corners if a forklift-forklift or forklift-pedestrian collision is imminent. Q-Track’s innovative system employs near-field electromagnetic ranging to detect proximity of forklifts and passive IR to detect pedestrians. Workers […]

Professor Steve Holland of the Milwaukee School of Engineering is an expert on UWB antennas and broadband matching. He reviewed Chapter 4 of my book as I was writing it, and he provided me with helpful feedback and insights on matching UWB antennas. His conference paper “Wideband Impedance Matching Techniques” […]

Another Great Review for The Art and Science of UWB Antennas



Can a preface itself have a preface? At the risk of being hopelessly self-referential, I suppose that’s how one might characterize this post. The preface to the second edition of The Art and Science of UWB Antennas follows. By way of introduction, the preface was actually the last part of […]
