Most recently, I have been interested in electromagnetic cloaking. In this case, objects of arbitrary shape may be coated with non-homogeneous and anisotropic materials with exotic properties (``metamaterials'') so that the object and the cloak itself become invisible, or almost invisible, to electromagnetic radiation. I have focused on the case where properties of the object are frequency-dependent and the incident wave is a narrowband electromagnetic pulse.
