| Summary: | Resonant cavities are a ubiquitous building block in science and technology. Here, Liberal et al. demonstrate theoretically the existence of resonators whose eigenfrequencies are invariant with respect to geometrical deformations of their external boundaries, by exploiting the unusual properties of zero-index metamaterials. |
