[ExI] Cool stuff to do for electrical engineers

I'm following this thread on Talk-polywell where they talk about
Woodward research and it strike me this exchange of a few days ago

http://www.talk-polywell.org/bb/viewtopic.php?p=127659#p127659

Maybe Spike or some electric engineer here could find it weird and
interesting enough to look at it.
And maybe we could get that damned flying cars before we need a flying
wheelchairs like Doctor Xavier.

Frequency yes, I recall they wanted an electrical engineer with a
master's to design a new power supply though. Apparently they don't come
off the shelf at the lower levels Woodward needs at the frequencies a
better thruster would operate at.

----

Did they ever specify what frequency range they needed, and into what
capacitance through what inductance, and with the varying parasitic
resistances? And for that matter if a perfect sine was best, or if they
needed more a catenary*?

*It needs a steady 2nd derivative of rate of charge, right? And if a
catenary, to what loading profile vs 2pi?

----

I think it was talked about either in this thread, or in a previous MET
thread. That was also where talk of the new dielectric and why it was
chosen was.

I might look it up later, but as I recall they wanted something in the
gigahertz range or even higher, and with a few hundred watts, apparently
they don't make power supplies like that off the shelf. There was also
trouble with a piezoelectric material that could run that high too.
