DesignNews should be embarrassed to print this pseudo-science. There is no such thing as scalar electromagnetic waves (except in very-specific situations which are not applicable here). If you follow the author's digital trail you'll find references to perpetual motion, space weapons, and fake medicine.
this is likely a joke based on Tesla folklore. The only so called scalar aka longitudinal E or B waves are special case modes inside a conductive waveguide, and even in that case are mutually exclusive. Either an E or B field can be longitudinal at one time. Furthermore, they do not leave the waveguide to the far-field, open space environment. Logical error in the article: If they will not act upon a condutor such as a Faraday cage, then they will not cause a current in your recieving equipment and will not go to the amp. Period. The E and B field in an EM trasmission are in phase in time, and 90 deg. to one another in space only ie. Flemming's rule of orthagonal orientation of E,B and physical Force.
Hello, anybody here remember their undergraduate electromagnetics classes? In a propagating EM wave in a lossless medium, E and B are in phase at all times. If there's a phase shift between them, it comes from gain or loss in the medium.
But of course there are lots of scalar waves known. The most common one is called "sound".
"Where does the inductive kick from an inductor or relay coil come from when the applied voltage is suddenly removed?"
Where does the current come from when a charged capacitor is suddenly short circuited? Collapsing electric field in this case, collapsing magnetic field in the inductor case. You certainly don't need a nebulous scalar space-time explanation for that...
The problem with this article is that the author has not determined the method of detection of this bi-polar signal. It simply went away and the author has "assigned" scalar waves" as a cause.
It has been my experience that RF signals having very high rise times in amplitude can drive apparently well shielded circuits crazy. My first experience with susceptibility of this sort was a particular UHF Motorlola handheld radio (MX300 series). These crystal controlled radios had a very abrupt transmitter turn on. Using one near just about any type of audio gear would generate a very noticeble "click". Later with the iDen (NEXTEL) and other TDMA products, it was observed that periodic clicking was heard in any nearby audio device or landline speaker phone .
I have no doubt, the microwave emenations cited by the author were the cause, however the detection phenomenon was left unexplored.
Could it have been so simple as a set/reset occuring in the overloaded op amp circuit hitting the rails? Perhaps the author was fooled by the triggering mode of his scope to beleive that it was a bi-polar signal?
I beleive this was simple case of the equipment being susceptible to the external microwave signals, that perhaps due to some "luck" were entering ductwork or cabling into the lab at just the correct instant of antenna position and pulse timing to deliver the full brunt of the magnetron. Perhaps it will return when the antenna rotation changes phase.
e It is articles like this and the following discusssions that make this site so facinating. All of the contributers are learned people, but cannot agree on whether or not the problem can even exist. Go back to early in the discussion and reread Ann R. Thryft's comment. How many things in history were impossible, before they were done?
So there is something in your field in which you have limited or no knowledge. Does that mean it is impossible fiction? I think it is more likely that when the only tool you have is a hammer, there is a great tendency to treat all problems as nails. The original author had a problem, tracked it to the source and made it go away. I say, "Great job', and let it go. The fact that I do not understand what transpired does not make it a lie.
When someone tells me to google something, I always wonder which of the 3 million hits I should read and believe. Google is only another tool in finding an answer, it is not THE answer.

In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
