    Microwave oven electric field mapping

    First of all, thanks to all of those who have offered their thoughts and advice. I thank you all! For the sake of those posting, I would like to clarify what I am looking for. I need to know two things: 1) The em-field distribution, specifically the location of "hot spots" 2) The electric...

    Microwave oven electric field mapping

    Hello again, Ok, I tried my ceramic idea and it didn't quite work as well as I hoped. There was hardly any sparking, it might have glowed occasionally, but not reliably enough to use it as a test. It did however get quite hot so there might be some potential if I could figure out how to...

    Microwave oven electric field mapping

    Thanks for the tips. Here's my progress so far: I put the graphite pencil lead in a ceramic standoff and put it inside a small glass bottle filled with nitrogen. My goal was to reduce the arcing and get just a glow, like a mini light bulb. Well when I put the thing in the microwave, it got...

    Microwave oven electric field mapping

    I found an old neon bulb and tried it out. It had regular wire leads and indeed the leads/electrodes I realize don't make much difference, the gas will glow whenever the bulb is in a peak. I am aware that there is modeling software for this sort of thing, however that won't help me. We are...

    Microwave oven electric field mapping

    Hello, I am trying to map the mode structures present in a standard microwave oven cavity. I am planning on using wet thermal paper and cobalt-chloride weather indicator paper to get an idea where hot spots are, but I still need a way to identify the electric field orientation. My current...

    Design of "dry box"

    I am currently working on designing a chamber capable of maintaining an oxygen free environment for a laboratory experiment. I need to have some idea of how long it will take to purge a given volume chamber, probably using cylinders of compressed nitrogen or argon. This is important as a...
