Hey Shell,I'm part way through the frustum build (metal is cut) based on the dimensions you suggested..QuoteFor a TE012, if that's your goal with a direct sidewall injection you would need to build to.Large diameter 0.280 mSmall diameter 0.160 mCenter Plate to Center Plate 0.2658 mDo you have a recommended location along the side-wall to locate the magnetron?(Or multiple locations to try)Thanks - your advice is appreciated. (Most of the tech involved in this project I'm fine with, however, the microwave magic I'm still learning as I go...)
A fundamental posit of quantum mechanics is that the deterministic initial conditions of a system do not define its evolution. (As in its actual mass-energy equivalence cannot be predicted simply by knowing the details you mentioned, because energy input into the system is run through what you might call a quantum function, i.e.. f(x)=a, where a is the actual energy state during measurement, x is the initial conditions, and f() describes some behavior. I'm deliberately avoiding probabilistic language because I tend to fall in the camp which views these quantum events as deterministic, specifically determined by pilot wave interference. That's getting too metaphysical for this discussion though, it wouldn't be wrong to think of the quantum interior of the emdrive as following a probabilistic energy evolution).

The question is do you still have the guide from the microwave?ShellI thought long and hard about duplicating Iulian's insertion point. Doc, MR T and I had many discussions on this. Here are the insertion points I experimented with:1) Centered on small diameter = null results2) Off-center on large diameter = null results3) Centered on large diameter = results per my test reportI avoided side insertion mainly because of copper mesh sidewalls not being as suitable as a solid end plate for mounting either waveguide of mag. Also, I did have concerns about Iulians design sputtering on bottom plate due to proximity of radome. Side insertion (my humble view only) should be waveguide only. Iulian had null results when side insertion point was centered if memory serves me correctly.I still have some doubts (no evidence however) that waveguide insertion will contain some EM polarity component (horizontal or vertical) that may reduce the effect compared to a non directional (omni) pattern from a radome.Regardless, this is my speculation only purely based on my experience with horn antennas. A non-circular waveguide will form polarity patterns: http://www.antenna-theory.com/antennas/aperture/horn.php

Am I right on this? We did run simulations on a single waveguide insertion into the bottom of the cavity parallel to the large plate and while the pattern for the TE013 wasn't perfect it still showed a very nice mode generation.https://drive.google.com/drive/folders/0B1XizxEfB23tR2NZaTZpeGE1ODAI'm not suggesting that the wide section of the magnetron be placed parallel but vertical orientated just like the picture with the bottom edge of the magnetron wave guide on the bottom outside section of the large plate.Unlike the simulation where the waveguide (I linked too) was shortened on the bottom that leads to some discontinuity in modes by making the wave guide on the bottom the length of the guide on the waveguide on the magnetron and "filling in" the missing section.

That's what we need to see.

It doesn't matter where the feed is placed in the cavity. Everyone has done it different and has adjusted the frequency to minimize the missmatch. If you maximize the power delivered to the cavity you will maximize the thermal response and therefore see a miniscule movement.

I read about the pioneer anomaly and was intrigued thermal radiation interacts with the vacuum of space.

I read about the pioneer anomaly and was intrigued thermal radiation interacts with the vacuum of space.The way the final report on the anomaly turned out it was not really a thermal interaction with the vacuum... At least not as it was explained.It was a very small imbalance in the way heat radiated from the satellite. A very small IR photon thrust effect, sort of. No QV or QFT involved.

Friday was finally my last radiation treatment. 8 weeks at 5 per week. Some days two treatments. They added a few on at the end.My pelvic, bowel and bladder regions are feeling like a chook that has been slowly cooked in a microwave. At my last doc interview was told the negative radiation effects will build up and peak in about 4 weeks, then drop away over another 4-6 weeks. Not really what I wanted to hear.Will get there.
If you saved the microwave magnetron you could use this to couple into the drive (see picture). The question is do you still have the guide from the microwave?
