Post at Scientific American guest blog on invisibility!

For those wondering where my science-related posts have been these days, I have at least a partial answer: I have a guest post on the Scientific American guest blog on, “Invisibility: After several years of research, it’s just gotten weirder”!  From the introduction:

Is it possible to hide something within an invisible cloak? It has already been over four years since the first groundbreaking theoretical papers on invisible cloaking devices were published, stirring up a near frenzy in the physics and optics communities. Since then, new results have come at a rapid and genuinely surprising pace, and news articles on the recent developments have been a bit overwhelming, even for a worker in the field. In this post, I thought I’d take a look at some of the fascinating results that have been published on invisibility, giving some perspective on how far we’ve come and how far we have to go!

I try and summarize some of the more unusual theoretical results about “cloaking”, showing how far researchers’ imaginations have taken the field.   Give it a look; for those who may have arrived at this blog from the SciAm guest blog post, you can find more of my writings on invisibility in my archives.
