Talk:Dielectric heating

message: Aren't cellphones thought to be more damaging because EMR can rip electrons off DNA and other molecules, creating free radicals?
No. See ionizing radiation and non-ionizing radiation. Microwaves are non-ionizing. Jmesserly 17:40, 9 April 2006 (UTC)

thread_title: Diathermancy is different from diathermy

message: There should be a section in this article as to why metal is not supposed to be put into microwaves. This article lacks that knowledge, and I do not have it. 71.87.114.122 (talk) 20:28, 2 October 2010 (UTC)
replies: text: It is not a universal rule that metal should not be put in the microwave; in fact you can find microwaves with metal racks (like a conventional oven). You shouldn't however, place metal objects with sharp points on it (e.g. fork) as it can create electrical arcs. This is already covered in the microwave oven page. 209.251.142.125 (talk) 21:03, 6 January 2011 (UTC)
thread_title:  Heating Metal 

message: Microwave ovens put out 1,000 watts commonly, and still the unfocused beam degrades exponentially in air, to the point that a couple meters is safe distance from an unfocused, operating magnetron. in contrast, microwave transmission antennas usually use 1 or 2 watts of power. they are focused/colliminated, and are yet still not powerful enough to cause the mentioned deep tissue burns.  —Preceding unsigned comment added by 71.137.148.217 (talk) 03:40, 9 February 2011 (UTC)
thread_title:  Microwave transmission dangers 

message: I suggest that diathermy be merged into dielectric heating.
As far as I can tell, both of them talk about the same thing -- using high-frequency electric energy to heat muscles.
Since they are different names for the same thing, I think they should be in the same article -- the same way that puma and mountain lion share one article.
Even if there are slight differences in how people use those terms, that difference can be discussed in the article.
(Merging the other way would also be fine with me).

thread_title:  merge suggestion 

message: I noticed that RF heating redirects here. However, there is also an article on radio frequency heating. If anything, 'RF heating' should redirect to that page unless dielectric heating and 'RF heating' are the same thing, in which case a merge is in order.--Subversive Sound (talk) 01:57, 9 March 2010 (UTC)
replies: text: I've pointed RF heating to Radio frequency heating for the moment, but I also think that Dielectric heating article ought to be merged with Radio frequency heating as it is a subset of that concept. 82.16.219.128 (talk) 12:51, 24 March 2010 (UTC)

text: Agree with merge. --Wtshymanski (talk) 22:17, 14 November 2011 (UTC)
replies: text:  Agree with merge as well. The parts of radio frequency heating that are not duplicated here can be copied to here (the section of that article that talks about the generation of heating is much poorer than this one's), and that article redirected to here.  Not all dielectric heating is done at RF frequences, but almost all of it is, since it is very inefficient at lower frequences (what is the lower limit to RF anyway? 1000 Hz?). We should make the distinction that "radio frequency" does not always mean production of actual "radio waves." A radio wave is something that propagates freely through space, like the microwaves that come out of a microwave antenna, or the radio waves that come out of a radio antenna. Dielectric heating uses electromagnetic signals at RF frequencies, but the fields between the capacitor are near fields, which means they are close to being static fields with much more E than B component, and they consist of virtual photons (rather like the induction fields inside a transformer), not real photons. Thus, they are not free-space, far field "radio waves," in the classic sense. Inside a microwave oven, there really do exist EM free-space microwaves, since the wavelength is far shorter than the gap between the metal walls. However, inside the metal plates of a dielectric heater, that isn't true, so the entire effect is near-field, without production or absorption of any genuine radio waves-- even if the frequences are RF frequences.

thread_title:  Second merge suggestion 

message: "RF heating holds promise as a way to process foods quickly."
Honestly, doesn't this sound ludicruous, in the light of this being a 70+ year old technology, and in fact predating microwave ovens by decades?
This is like saying that AM radio "holds promise" of longer range, cheaper operation over FM. 38.125.36.194 (talk) 14:35, 21 August 2013 (UTC)
thread_title:  "Holds promise"?! 

message: Intermediate frequency normally means a local frequency in a superheterodyne receiver.  Exactly what does "intermediate frequency" mean here?  Is it a subset of the microwave band? Comfr (talk) 18:33, 2 January 2016 (UTC)

message: Hello fellow Wikipedians,
I have just added archive links to  on Dielectric heating. Please take a moment to review my edit. If necessary, add  after the link to keep me from modifying it. Alternatively, you can add  to keep me off the page altogether. I made the following changes:
*Added archive https://web.archive.org/20100706231044/http://homepages.ed.ac.uk:80/ah05/basicintro.html to http://homepages.ed.ac.uk/ah05/basicintro.html

thread_title:  External links modified 

message: The entire section on dialectric heating has been marked as requiring citations for over three years as of June 2016, so I added a page tag. If I get some spare time I'm going to try and dig out some physics books on the subject 2.24.56.146 (talk) 23:28, 18 June 2016 (UTC)
thread_title:  Dire need of citations 

message: The article states, 
"frequencies in the range of 10–100 MHz are necessary to cause dielectric heating, although higher frequencies work equally well or better," 
which is a bit nonsensical (like an ad saying "save up to fifteen percent or more"). It sounds like a frequency of at least 10 MHz is necessary, with no upper bound.
