Maybe if we used sulfur hexafluoride gas SF6 as a wave guide quench gas, we could push more power. I guess we would have to shield the outside as well as the inside.
Microwaves _are_ analog! They're just in one of the gaps in our analog ranges of perception. Too fast to hear; too slow to see. As far as I know, Old Hack hasn't uploaded anything that _isn't_ about analog, and I love him for that. None of that digital rubbish on this channel!
So what does that mean for waveguides in space, it looks like its down to a few watts would that be right? or is voltage breakdown in space much higher as there is no air
The next regime of microwave mayhem for space applications is known as multipaction or multipactor. It is a resonance breakdown phenomena requiring both a vacuum (no air) and radiation (free electrons) environment.
@@oldhackee3915 Your plot is fine. There is a lot of interesting Physics summarized in a Paschen Diagram, especially that the x-axis is product fo frequency*dimension.
Thank you for your great videos!!
Thanks very much.

Thanks for the comment. That sounds interesting.
If the capacitance not change and dielectric looses not going to be mutch higher than as air use as insulator.
@@Duracellmumus So does that mean we can't use wave guides in the vacuum of space without the dielectric of air?
Please upload some analog stuff 😊
Too much microwaves for you?
@@oldhackee3915 There's never *too much* microwaves!

The voltage breakdown goes back up in a vacuum. The Wikipedia page on Paschen’s Law the graph is better than mine as it approaches a vacuum.

Look-up Hatch & Williams regarding Multipaction.
Thanks for the comment.
