That's a good point. A "hot-spot" in some un-occupied section of the microwave isn't wasting energy. There is no load at that location so there are no losses beyond the usual path losses due to distance and a non-vacuum medium, right?
Perhaps I should be asking about power transfer. In a...
Oh, the waveguide dimensions are 3.4 x 1.7. That's close to what I have seen in torn down microwave ovens. So my question should be: how to build a resonant chamber with the smallest number of hot spots. I think the answer is going to require simulation. Well, this concludes my idiot microwave...
I don't know if the lack of response corresponds to the level of traffic or the quality of the question. Let me ask in another way:
Given that a waveguide for 2.4 GHz is something like 24 x 12 inchs and an 800 W magnatron is the power source at a right angle 1/4 wavelength from a backshort...
I recently was reading about traditional inorganic analysis of an unknown alloy. From an idiot's POV, it's a series of precipitations, interleaved with centrifugation or filtration, followed by another precipitation, etc. Some color changes and lots of fussy details, like how to dry a...
I stumbled on a guy who uses a appliance type microwave oven to melt metal (link below). He makes a kaowool enclosure for home-made silicon-carbide crucibles. The kaowool absorbs little in the "microwave" bands and silicon carbide absorbs strongly...
I'm working on a design that has several joints that move very little and under fairly high load. At the moment it appears that a conical plain bearing is the best solution. To get NZ/P up to about 10, I'll need to use fairly viscous grease. CMD #3 was my first thought but there's no viscosity...
