Abstract
"But I went to work—like a slave,” said the Invisible Man. “And I had hardly worked and thought about the matter six months before light came through one of the meshes suddenly—blindingly! I found a general principle of pigments and refraction—a formula, a geometrical expression involving four dimensions. Fools, common men, even common mathematicians, do not know anything of what some general expression may mean to the student of molecular physics. In the books—the books that tramp has hidden—there are marvels, miracles! But this was not a method, it was an idea, that might lead to a method by which it would be possible, without changing any other property of matter—except, in some instances colours—to lower the refractive index of a substance, solid or liquid, to that of air—so far as all practical purposes are concerned." – from Chapter 19, The Invisible Man by H.G. Wells (1897)
In this view the history and several selected topics associated with the fundamental properties of metamaterials. I will show how wave interaction with such materials can lead to interesting, unconventional features not observed in standard media. These physics characteristics can lead to exciting engineering concepts with future potential applications such as invisibility that is pictured above. After reviewing some of these concepts, I will present the novel building blocks of metamaterials, namely Archimedean Spiral Resonators, the structures that I have been working on since 2005.
