Limitations on bandwidth-integrated passive cloaking
The authors lay out a framework for understanding the optimal performance of practical electromagnetic cloaking devices, providing new theoretical insights for future designs and showing how perfect cloaking is impossible even for a vanishing bandwidth for finite cloak sizes with bounded refractive index contrasts or material losses. The framework is exemplified by designing a cloak for a circular object in two dimensions.
