My exact thoughts, it deserves an award for outstanding research and production. I also love the historical bit at the end mentioning how the technology was little understood in the beginning. Supposedly, American scientists were initially amazed at how such a small device could create so much power.

[@АнтонАлександрин-ч8х]

The key principle of the magnetron remained unmentioned. The electrons tramsmit their potential energy to the high-frequency electric field thus increasing its power. Without cavities and HF-field electrons move by trochoidal trajectories around the cathode and never reach the anode. But in presence of HF-field electrons interact with it, losing their speed and moving closer to anode. This leads to decreasing of electrons' potential energy (which is determined by their distance from the anode). This energy is transferred to the electromagnetic field.

[@revatis2571]

This might be silly question but can u explain that how in such cases electron's potential energy is determined by its anode from anode? why when velocity of electron decreases potential energy decreases? Thank you

Thank you for bringing our attention to missed details . But Maxwell states that all charged particles have electric fields which in turn generates the magnetic field perpendicular to it . The HF would mean electric fields turning positive and negative very rapidly . The moving particles would have their own fields . The fields are waves . There would be waves interaction. The waves would have two dimensions . Place the rest of information in reply to further my understanding

[@1272-f9v]

​@@Adolf0is0winner The waves are always, difference in density between different particles, no matter what the environment is... in an environment of different particle sizes, it is possible to generate waves of different sizes by compressing some of the particles. Empty environment, without any particles, does not exist. All smallest charged and uncharged particles are electric fields in different densities. Density of the particle electric field determines of what atom do we have.

[@infatum9]

Thanks. Since detecting an object requires a return wave propagation from a reflected object it would be nice to hear how the return wave gets processed.

[@_sunsor]

The short version: return wave has predictable frequency, big antenna with special shape points toward where reflection should be coming from, given speed of light thru air, measure time between outgoing pulse and incoming pulse to measure distance. Size of object corresponds to strength of reflected signal.

[@busimagen]

adding to sunsor comment above : S send pulse, R = return pulse S______________R__ far S_____R___________ near Simple math on how long it takes to receive the return pulse will tell you distance. The pulse is directional, and if you rotate the sending antenna, the turning of the antenna is much much slower than the speed of light, so the return pulse will come back before the antenna has turned much (so, it is basically still pointing in the same direction). So, if you receive more than 1 return pulse, you have more than 1 contact in that direction. This makes it easy to use a cathode ray tube (the kind one would use for an old oscilloscope) to plot the signal. All the CRT needs to do is scan in the same direction that the antenna is pointing, and shoot electrons any time a return signal is detected, and the time it takes for the electron beam to make one scan to the edge of the screen removed the need to actually do any math (it just comes out as a result of the time it takes to trace/not-trace the line). If you do it digitally, though, then you actually have to do a bunch of processing before you can display anything. Using a CRT is thus a much much simpler process (just scan a line from center to edge in the same direction as the sending antenna, shoot electrons when there is a return signal received), adjust scan line speed to adjust zoom (slower scan line speed gives further out zoom; faster gives closer in zoom).

[@infatum9]

@@busimagen thanks for expanding. I presume it is almost the same principle as for ultrasonic sensor in Arduino, with a difference in speed, that is instead of the speed of sound 340 m/s one has speed of light 300 000 km/s. And as you pointed out, the speed of light/radio wave is way faster than the speed of rotating radar. I thought the video could have gone into these details as well, but for some, I guess, it would be over the head.

[@LoanwordEggcorn]

[@Lesjaye]

Best explanation I’ve seen so far. Amazing that anyone could think this device up!

[@johnedwards1685]

An analogy of a magnetron is a whistle like that which a football referee would use. Think of the metal body of the whistle as a single tuned cavity (tuned to the pitch of the whistle). When you apply power to the cavity by blowing hard into the whistle, the cavity oscillates at its tuned pitch producing a loud noise very efficiently. The output (in this case noise) is transmitted via a port to the outside world. A magnetron is similarly a tuned cavity (actually a ring of cavities), and high voltage, high current provides the power. The magnetron output is a single frequency just like a whistle but at a very much higher pitch. That output is transmitted to the outside world by a waveguide (pipe). An electric whistle.

[@brassj67]

Knowing what I know now, it seems so obvious. The genius part was to get the electrons to loop around unlike a normal vacuum tube where the electrons travel in a straight line. TV cathode ray tubes use the same principle but with electro magnets to bend the election beam to the correct part of the phosphor coated screen through a fine mesh mask. This uses very strong permanent magnets to cause the electrons to loop out then back in just like solar flares on the sun
