ABSTRACT

Recently there has been quite a flurry of activity concerning the use of so-called metamaterials for various optical and electromagnetic applications. One particular application has been ”cloaking”: to create a space that itself, together with any object occupying part of this space, is completely ”invisible” to electromagnetic (boundary) observations. One prominent approach to ”cloaking” is based on metamaterials obtained by clever use of ”push-forward” mapping techniques. As it happens, the same mapping techniques proposed by engineers and physicists to generate such metamaterials had previously been studied by mathematicians working on a geometric version of the Impedance Tomography Problem.

GOALS

The idea behind this workshop is to bring together selected (electrical) engineers, applied physicists and mathematicians, whose work have already had, or could very possibly in the future have implications as far as metamaterials and cloaking are concerned. Among electrical engineers and applied physicists this would of course involve people who have actual experience with the ”manufacturing” of such electromagnetic metamaterials. From the mathematical side it would naturally involve people whose past work have had significant impact on electromagnetic imaging problems – and the associated reconstruction limitations. Very interesting (and still largely open) areas of research involve:

(1) cloaking ”at all frequencies”, and furthermore not just for
time-harmonic Maxwell,

(2) the construction of efficient approximate cloakings, and

(3) a deeper understanding of the efficient ”manufacture” of such cloakings. Even though the above discussion
centers on cloaking and metamaterials obtained by mapping techniques, it would be quite natural to include other closely related subjects.

Two subjects that are on our “supplementary” list are

(1) materials with negative index of refraction, and their use in cloakings, and

(2) metamaterials designed to create other optical- or electromagnetic ”illusions”. The workshop will provide a forum to exchange and stimulate new ideas from different disciplines, and to formulate new challenging problems whose solution will have impact on applications.
