PDS: Let's parse this a bit better... in English (you know, like in the movie Pulp Fiction: "English, do you speak it?" <g>) To do this, first let's get rid of the fancy, not really necessary, somewhat misleading language constructs... Susceptor = Transducer There! That's better! That's because a "susceptor" IS a transducer -- at least as far as Microwave radiation goes... Here, for reference: https://en.wikipedia.org/wiki/Transducer https://en.wikipedia.org/wiki/Transducer >"A transducer is a device that converts energy from one form to another." Microwave = Energy, Heat = Energy, if a Susceptor converts microwave energy to heat energy, then by definition it is a transducer. (That or Wikipedia is wrong... and we all know that that never happens...<g>) OK, so now that we know that a Susceptor is really a Transducer, what next? Well, here's the thing... If you read the last line, it said that Susceptors, er, Microwave Transducers, can apparently be made with "carbon-based coatings". Why is that interesting or important? Well, consider the following... If you put metal into a microwave... the metal acts as a transducer, but no so much for heat, so much as electricity, high voltage electricty! That metal will turn that microwave into high voltage electricity sooner than quick! That's why metal objects -- should not be placed in microwave ovens... But now, here's the thing! Carbon (at least in its common forms, like charcoal and graphite (note we are not talking about graphene here!)) is a semiconductor. In other words, it's sort of electrically conductive, and it sort of isn't! It's sort of the halfway point between a non-conductor and metal! And here we see that apparently it could be used in a microwave, to generate heat! So now, with all of that background... I have to ask the following set of questions: 1) What's the exact relationship between heat, electricity, and microwaves? 2) How does that relationship vary by the underlying material placed in a microwave, specifically by the electrical conductivity of the underlying material? 3) Electrical transistors can be made; we know all about them; they are commonplace; but can microwave transistors, and/or heat transistors be made? And again, if so, what is their exact relationship to the underlying material? I think I read somewhere that they have microwave transistors -- so they probably already exist. But, that doesn't invalidate the other questions... Note To Future Self: Research this phenomena... Also... how does/would frequency of the microwaves, as well as positioning in the microwave cavity (that is, the microwave oven) affect things? And... can other types of transducers (sound, light, other ranges on the EM spectrum) be made for microwaves?
