Metamaterials are rationally designed man-made structures composed of functional building
blocks that are densely packed into an effective (crystalline) material. While metamaterials …

In this review, we give a brief introduction to the application of the new technique of
transformation acoustics, which draws on a correspondence between coordinate …

We adapt tools of transformation optics, governed by a (elliptic) wave equation, to
thermodynamics, governed by the (parabolic) heat equation. We apply this new concept to …

Inverse problems arise from the need to interpret indirect and incomplete measurements. As
an area of contemporary mathematics, the field of inverse problems is strongly driven by …
