== Organization needed == 

 The lead section of this article does not accurately convey the current content. It implies that, at the very least, the following topics will be described and discussed: 

 * Anomalous localized resonance 
 * Diploar scattering 
 * Tunneling light transmittance 
 * Sensors and active sources 
 * Transformation optics 

 Just skimming over this article, this doesn't appear to be the case. In fact, transformation optics seems to pervade more of the article than its heading suggests, while none of the other terms are defined or even used in an easily recognized form in the remainder of the article. And, of course, there's the ever-present problem of jargon-dense information without any more readily accessible introductions to each subtopic. 

 It seems to me that the chief problem of this article is that it has no organization; i.e., a well-defined subject that can be broken down into subtopics and arranged in a logical flow. I only ever got as far as an physics minor in college (not optics!), and my head spins trying to assess the content as it is. But I suspect that it might be assembled into something like this: 

 * [Lead section] – mostly done, although (A) metamaterial is not defined (anywhere in the article, in fact; a link is not enough), and (B) the last sentence is jarringly specific and should be moved elsewhere 
 * Science of cloaking – what it means to "cloak" something, or render it invisible; why it's a challenge (it could even be called "Quest for invisibility" if you want to get dramatic) 
 * Theoretical approaches – introduce subject, with at least a few sentences on why metamaterial is part of this article's title (i.e., why they're part of these cloaking approaches), then provide sections in the order described in the lead section 
 ** Anomalous localized resonance 
 ** Diploar scattering 
 ** Tunneling light transmittance 
 ** Sensors and active sources 
 ** Transformation optics 
 ** Broadband ground-plane cloak (?) 
 * Proposed applications 
 * Institutional research 
 * See also, etc. 

 Assuming this is a reasonable organization of the content, all the remaining material should go under one of these headings. (Even if transformation optics winds up being a huge subsection, the other approaches should have at least summary paragraphs as placeholders. The structure will show potential editors what's needed.) If they don't fit, then my suggestion isn't adequate, but some logical order and flow needs to be imposed. Also, the current "In the news" section doesn't belong here at all. If there is meaningful information to contribute from these media sightings, it should be incorporated into the text of the article with appropriate citations. 

 I realize that this article has gone through a few major transformations, which no doubt contributed to the problems. I hope my suggestions are of some use in fixing them. ~
