RF & Microwave Magazine Article Archive - 2021

If you are like me, you spend a lot of time reading articles from technical magazines. Sometimes I read the entire article, but usually I just scan the text for highlights and look at the schematics, block diagrams, and charts / graphs. Often, I want to go back and find an article but cannot recall where I saw it. A Google search will usually eventually reveal a hyperlink to the article, but a lot of times it takes a lot of digging. Since my key interests are not necessarily the same as RF Cafe visitors, an attempt will be made to catalog all of them. If there is a magazine not included here that you would like me to include in the list, please send me an e-mail and I will try to incorporate its articles, too.

What's the Difference Between EMF and Voltage?

Whenever I see John Dunn's name I think of the English poet John Donne, but that's my problem. Mr. Dunn wrote an article for EDN magazine entitled, "What's the Difference Between EMF and Voltage?" He begins: "I once read this very strongly-written essay about the difference between electromotive force (EMF) and voltage. The author seemed like he was on some kind of holy crusade and was intensely determined to set his readers straight on fundamental truths that were NOT to be dismissed by infidels. I read his words, but for all of the vitriol, I didn’t understand him at all. Recently, I decided to take a closer look at the issue. EMF is given in units of joules per coulomb. The frame of reference for this definition is for any device that uses a non-electrical source of energy to impart electrical energy to a unit of charge, which if given the chance, will flow somewhere..."

Overcome Stray Magnetic Fields with Active Field Compensation

"As the EV market grows, so does demand for robust magnetic field sensors within these vehicles. Stray magnetic fields may diminish the accuracy of these sensors, though, which is where active stray-field compensation comes to the rescue." So begins Frederik Berstecher in his article entitled, Overcome Stray Magnetic Fields with Active Stray-Field Compensation, posted on the Electronic Design website. Continuing, "The electric-vehicle market continues on a serious upswing: Allied Market Research forecasts show it will reach $802.81B by 2027, up from $162.34B in 2019 [can they really estimate to 5 significant digits? - KRB]. Such growth also pushes the need for additional magnetic field sensors within these vehicles for position detection. The sensors are robust enough to withstand a variety of harsh environmental conditions, temperatures, vibrations..."
