Orphaned references in Split-ring resonator

[edit]

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of Split-ring resonator's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

Reference named "AAAS2":

  • From Metamaterial antennas: Shelby, R. A.; Smith, DR; Schultz, S (2001). "Experimental Verification of a Negative Index of Refraction". Science. 292 (5514): 77. doi:10.1126/science.1058847. PMID 11292865. {{cite journal}}: More than one of |first1= and |first= specified (help); More than one of |last1= and |last= specified (help); Unknown parameter |coauthors= ignored (|author= suggested) (help)
  • From Negative index metamaterials: Shelby, R. A. (2001). "Experimental Verification of a Negative Index of Refraction". Science. 292 (5514): 77–79. doi:10.1126/science.1058847. {{cite journal}}: Unknown parameter |coauthors= ignored (|author= suggested) (help)

Reference named "radiation-properties":

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 15:10, 19 October 2009 (UTC)[reply]

Alright

[edit]

So this article needs a major revamp. Given the vast literature on SRRs, how about something like this:

  • Equivalent circuit model using lumped elements or T-lines or whatever, including the resonant frequency as a function of effective inductance/capacitance
  • Bulk/macroscopic model for many isolated SRRs
  • Related effective material particles, like Swiss rolls, omega elements, ELCs rotated 90 degrees, etc
  • Extension to optical frequencies with a link to photonic metamaterials articles
  • Experimental validation (Shelby/Smith, etc)

That would turn it into an article really about the SRR, with plenty of places to add citations to all the literature that's already here. Also not OR, since there are several papers floating around dealing with detailed analysis of the SRR itself. Off the top of my head, Popa and Cummer have one from maybe 2006-2008 about modeling an SRR. I will go through these and start gathering some more concise cites, before going through a major edit of the structure of this article. RFenginerd (talk) 02:46, 25 May 2010 (UTC)[reply]

Sounds good. I haven't worked on this article in awhile. The orginal organizational structure I had in mind was chronological of sorts. Yet, although this organizational scheme works for the other metamaterial articles, it doesn't seem to be as applicaple here. SRRs are SRRs. I don't see how equivalent circuit models actually work in this article. I have discussed this somewhat in Metamterial antennas, where there are sections regarding T-lines. We could do a spin-off article of T-lines and discuss lumped elements, etc. in that article. However, if lumped elements work here, then feel free to work it in, somehow. What do you think of the spin-off article idea? There is no metamaterial article that includes Swiss rolls so that could work here, I suppose. Your other ideas sound good as they are.

Why up to 200THz?

[edit]

It is said in the first paragraph that "Their purpose is to produce the desired magnetic susceptibility (magnetic response) in various types of metamaterials up to 200 terahertz. I've seen many papers that discuss the applicability of SRRs to frequencies up to 600THz; for example see this PRL paper by Pendry, et al.: Saturation of the Magnetic Response of Split-Ring Resonators at Optical Frequencies. What is the purpose/meaning of that statement?(maybe refers to the SRRs that have been manufactured so far?) Physicsch (talk) 19:49, 16 May 2014 (UTC)[reply]

Is it possible the statement is just outdated? I have to do some reading but I believe metamaterials is still active field of research Penrose sachdev (talk) 02:09, 6 January 2024 (UTC)[reply]

Images needed

[edit]

The section "Several types of SRR" ould benefit greatly from images in my opinion to show the various designs that have been fabricated. I would also suggest chaning the subheading to "SRR configurations" or "SRR geometries"
