793:(having a background in optics) was not yet aware of the concept of Bloch waves from semiconductor theory. So back in the nineties, the author (independent of Felix Bloch) came up with the expansion himself, and only later realized (unfortunately, after publication) that Bloch had already discovered the exact same series expansion over half a century earlier, in connection with solutions to Schrodinger's equation in periodic crystals. So, out of deference to Felix Bloch, the name of the method was changed from "Spectral Domain - MoM" to "Bloch Wave - MoM." The author felt then (and still does) that it is correct to credit Bloch with the periodic field expansion that has been known under his name (in the semiconductor world) for decades. So whether it's a periodic electron wave function in a semiconductor or a periodic optical wave in a photonic crystal, it's the exact same mathematics in both cases, and as a result the Bloch name can rightly be applied to both applications.
647:. The current page should be deleted as per Knowledge policy; if you do not believe it should be merged into Frequency selective surface, please provide an alternative. It is standard practice to begin a new section in the article and merge the contents in there, it would not be ambiguous and could clearly state any differences with the rest of material in the Frequency selective surface article. Also, if you have knowledge on the subject, would you mind providing even a single reference for this method that brings together "Bloch waves" and the MoM method? If the article contained any of those, I would not have nominated it here.
258:(see talk page there), we have edited that article to remove references to Bloch wave and moved it to "Bloch's theorem". After noticing this, this article is curious. I have personally visited each of the IEEE articles and the Phys. Rev. B article as well as gained access to the book by Harrington and have verified that not one of them mentions the term "Bloch wave" (nor "MoM method" or even "Bloch" - no reference to the person or theorem) I believe the literature cited is discussing the Method of Moments and there is already an article
821:) "generally prefers the name that is most commonly used (as determined by its prevalence in a significant majority of independent, reliable English-language sources)". As Myxomatosis57 has said, it is strictly against the rules to use titles that do not appear in reliable sources. You're free to think the terminology in the established literature is misguided, but Knowledge is not the place to correct the record.
512:: I must admit that I didn't really dig into or give thought to the topic while technically editing it back in May. The method discussed here appears to be spectral-domain method of moments with periodic boundary conditions for PEC scatterers; I don't really think that this very specific formulation for periodic media deserves its own article (but MoM, as a separate article from BEM, does, in my opinion).
792:
There is a reason why the term "Bloch wave - MoM" does not appear in the literature, including in either of the two IEEE Aerospace Conf. papers cited in the article. When the research was done for those two papers, and even up to (and several years past) the publication of the two papers, the author
715:
Yes, it appears to be scientific literature, and that is fine, but none of these sources discuss the MoM (or at least they never mention MoM or method of moments) and so everything provided is totally irrelevant to this discussion. When I said scientific literature, to be clear, I was talking about
603:
The
Harrington and Rumsey references relate to the concept of reaction, which is central to ALL (spatial and spectral domain) moment methods and is separate from the Bloch wave formulation. In fact, it was the bringing together of these two concepts (MoM and Bloch waves) that makes this method

Do you know what the actual name of this specific method is? We can move the page to whatever its standard name is given there are enough (quality) references to ensure its notability. Also just so you know, Knowledge is not a textbook and it should not be relied upon for education, especially
516:'s and Rumsey's articles were cited to be "complementary" to the theory behind the formulation, I believe. I've seldom seen the term "bloch wave" in photonic crystal/periodic media literature; in this case, the full title appears to be the original contributor's own construct, failing
270:, but it is obvious this article should not exist, for many reasons: It lacks notability as a term and it lacks any citations on the actual topic it claims to be discussing. I am very confused how "Bloch wave" became so prolific on Knowledge when academia does not support the term.
