I moved these sections to the bottom of the article so that they can be worked on there and the first part of the article can be read while these are being worked on. Steve Quinn (formerly Ti-30X) ( talk) 05:46, 29 October 2009 (UTC)

"In December 2005, phononic crystals were proposed by a Physics World online article (Physicworld.com). Physics World is a membership magazine of the science society, Institute of Physics."
Perhaps the reference should state the "popularization" of phononic crystals. They were known long before 2005, especially in the one-dimensional case. Consider the surface acoustic wave reflector grating, a distributed Bragg reflector which is a special case of the 1-D phononic crystal. —Preceding unsigned comment added by Rwestafer ( talk • contribs) 15:46, 15 December 2009 (UTC)
The first comment on Talk:Metamaterial included the question:
And received the answer:
I would like to ask the same question about phononic crystals, because the article doesn't consider this question and I haven't been able to answer it from other internet sources. If the size of the features relative to the wavelength is a crucial part of the definition of a metamaterial, surely it should be in the article? Thanks. DorrieC ( talk) 09:59, 3 August 2011 (UTC)
Hello fellow Wikipedians,
I have just added archive links to 6 external links on
Acoustic metamaterials. Please take a moment to review
my edit. If necessary, add {{
cbignore}}
after the link to keep me from modifying it. Alternatively, you can add {{
nobots|deny=InternetArchiveBot}}
to keep me off the page altogether. I made the following changes:
When you have finished reviewing my changes, please set the checked parameter below to true to let others know.
An editor has reviewed this edit and fixed any errors that were found.

In the "Analogues" section: "Flat slab focusing, which can result in super resolution, is similar to electromagnetic metamaterials." The article doesn't explain how super resolution is relevant to acoustic metamaterials and the linked article in Wikipedia does not hint for any non-optical applications for the terms. Maybe a sentence or two of explanation is in order? — Preceding unsigned comment added by Barruktp ( talk • contribs) 16:35, 8 October 2019 (UTC)
User Laura sf was right, this article needed more copyediting before removing the tag. I've done more work on it but didn't want to remove the tag again without trying to get some feedback. I've (boldly) removed quite a bit of content which I thought was redundant or not relevant. I rewrote some sections for clarity, removed repeated wikilinks, and deleted a few references that were excessive. I have some background in acoustics but not in metamaterials, so I didn't touch some sentences that seemed badly written but which I didn't fully understand. This article would benefit from further work to make it more understandable, specially from a subject expert. I will wait to see if there are any objections before removing the copyediting tag again. -- Alan Islas ( talk) 00:26, 22 July 2020 (UTC)
