AMT in the MW oven
Teon:
There is just something about modifying a microwave that is just a little, well, unsettling. Just out of curiosity, how did you find the exact wavelength that your microwave operates on? They didn't randomly include that in the owners manual did they? When I think about it, every microwave I've ever owned has been 2nd hand; I've never seen an owner’s manual for one.
Rhodium:
All microwave ovens operate at the approximately same frequency (~2.5 GHz, or ~12cm), as 1) they are only allowed to generate RF noise at a certain band as to not disrupt any radio traffic, and 2) Microwaves of that frequency are the most effective to heat food with.
There is tons of info on things like this on the net, try google.
Organikum:
as long as the pipe's diam. is smaller than ½ the wave length and longer than 1 wave length nothing leaks out
--- End quote ---
The diameter must be smaller than 1/2x (one half) the wavelength - 6cm or less is correct so. If it would be 1x the wavelenfth it would make a nice waveguide.
The soldering of the tube to the inner metal cavity is essential. NEVER just stick the tube just in. This would make a nice "slit antenna" with some db win. Outch.
I was rereading this thread and without nitpicking I believe this being necessary to be added for safety.

Naaah, not really. Microwave heating mostly works because of the absorbtion of mw energy by water molecules (ever wondered why you could never get dry rice warm in a mw oven?)
I've seen a graph of the absorbtion of microwave radiation of water as a function of wavelength, and that showed a broad peak with its maximum at about 18 GHz or so. So basically it doesn't matter that much which frequency you use. The only requirement is that you're able to dump lot of energy in it, and that it's pretty sturdy and cheap to build. And in that respect it makes some sense to sit on the left hand side of the absorbtion graph.
kjb1891:
Does anyone know of any possible substitution for nitroethane(typo in the original post by hest) in this synth? Regardless of yeild differences.
