TLTW: Sheets soaked in Water held in front of you will absorb and metal sheets, even as thin as aluminum foil will reflect the waves, because of photons n protons n sheeiit.

Legit!

That 120hz drone coming from the microwave.... so soothing.

Drawing myself a diagram of with and without the horn, trying to understand the bit he said about the horn being an impedance match device. He mentioned it had to do with reflections of the microwaves. I can see at certain angles (actually many certain angles) without the horn, there are places where the reflecting wave is the opposite in phase as the outgoing wave which of course attenuates the outgoing signal (I guess that's the impedance). With the horn installed, the "field of view" where reflections can make it back to the source is much smaller. Hope I'm describing this right.

I suppose how well of an impedance match you're getting depends mostly on what type of surface(s) you're aiming the thing at. Point it over here, all of the energy is being delivered to the load... whereas pointing over there much less energy is being delivered.. Horn or no horn.

Kind of blowing my mind right now. I'm used to impedance matching over a transmission line... but when your transmission line is... space... I'm feeling a little lost.

Clearing my schedule for the day, there's reading to do.

E: I put several RC antenna circuits on paper in front of the microwave transmitter. With the horn installed, more of the transmitters photons are able to reach the antennas by bouncing off of the sides of the horn. That's more power to each individual load. So I guess that technically looks like impedance from the transmitter's perspective.
