CrystalMagic Posted February 18, 2023 Share Posted February 18, 2023 Tell me if there are very small emitters of microwave waves? Microwave emitters the size of a pea grain, for example? Although it is possible and more if there are no such small ones. Do they exist or can they be made? Link to comment Share on other sites More sharing options...

The smallest microwave wavelenght is 1mm so a quarter wave antenna is only 0.25mm. Many insects have antenna that are in the 0.25 to 5mm length range and some are known to respond strongly to microwave radiation. Equally artificial antenna of this size can easily be constructed. 1 Link to comment Share on other sites More sharing options...

All the electronics and the energy source? Really small circuits are certainly possible. Commercially-available ones a little larger than your parameters can be found, and could be made smaller.

The size limitation would I think enforce a waveguide selection sized for something in excess of ~75 GHz. What kind of application do you have in mind? 1 Link to comment Share on other sites More sharing options...

You could see the beginning of my thought in the topic Reflections on science. I was talking about freezing. Microwave technology is what can be a defrost option. In addition, I was simply interested in the mysteries of microwave radiation. Like EmDrive. You heard about it? I think microwave radiation has a lot of mysteries?

Are microwave technologies a weapon? I didn't think about it. I'm sorry if I offended you! I think that a lot of things can be used as a weapon. I heard that many medical technologies can be weapons. You may not believe me. I don't know how to prove it to you. My interests are not related to weapons. The problem with science, I think, is that many technologies can be used as weapons. I was just wondering if it is possible to improve the defrosting of organs by using internal microchips with microwaves? I was wondering if this is possible? It probably sounds stupid. I'm just new to this topic. Even if you suggest that I would really like to know this. So you think I would work on it? Do you think I would ask this on some kind of open forum where they write all sorts of jokes? I think high-class specialists are working on this and they do not waste time on forums. Why do I feel like this is some kind of joke? You can think whatever you want. But I have no goals to create something dangerous. If I have committed a violation, then delete the entire topic and my messages. Although I do not think that for this you need my consent? But the topic remains. Although I can tell you that you don't have to write to me about it. If you take it that way, then I withdraw my question. Don't text me back! I tell everyone don't answer this question of mine. I'm deleting the thread with my question. Link to comment Share on other sites More sharing options...

I’m not sure why you would need an internal transmitter, since microwaves can penetrate. Link to comment Share on other sites More sharing options...

Primarily for military applications? My microwave oven disagrees. So does my wi-fi router. There’s nothing under discussion here that can’t be found in a textbook, news article, or as a reasonable extrapolation of other easily-accessible information. You can swallow various devices as medical diagnostics with wireless communication for data collection. So these are slightly larger than pea-sized https://www.mayoclinic.org/tests-procedures/capsule-endoscopy/about/pac-20393366 “in 2006, the U.S. Food and Drug Administration approved the SmartPill, an ingestible capsule that measures pressure, pH, temperature, and transit time as it passes through a person’s gastrointestinal tract.” https://www.inverse.com/science/ingestible-sensor-digestive-system 1 Link to comment Share on other sites More sharing options...

Point understood. 22 hours ago, CrystalMagic said: Tell me if there are very small emitters of microwave waves? Microwave emitters the size of a pea grain, for example? A waveguide that can fit into a pea restricts the emitter to W-band or higher. Such wavelengths do not penetrate more than skin deep. Not much use for defrosting purposes.

Like EmDrive. You heard about it? I think microwave radiation has a lot of mysteries? Well microwave radiation is certainly a large, wide ranging subject in its own right. So I was going to ask you "In what context are you interested in microwave emitters and their construction ?". But clearly microwave emission is happening all the time around us or there would be no microwaves! If the EmDrive works at all, which I doubt, it is all in the tranmission aspect (ie waveguides). So pony up and focus your question please. I take it you are not interested in the biological aspects I mentioned. Note the heating effect of microwaves depends on indirect heating of water or sugar molecules which in turn heat the whole material in you microwave, but as Seth noted these are not the sort of microwaves you generate from pea sized emitters. Here are some real figures and a calculator. Quote The cavity is 93.6 mm inside diameter and 50 mm high, and has a resonance frequency of 2453 MHz, as calculated above. This corresponds to the international frequency for 802.11 wireless internet, as well as commercial microwave heating. https://www.everythingrf.com/rf-calculators/cavity-resonance-frequencies Edited February 19, 2023 by studiot 1 Link to comment Share on other sites More sharing options...

If it is not perceived negatively in this forum? Are there computer programs in the public domain that can calculate the effects of microwave radiation to defrost organs?
