Metamaterials designed for enhanced ENZ properties]{Metamaterials designed for enhanced ENZ properties
Matias Koivurova, Tommi Hakala, Jari Turunen +3
We examine layered metamaterial structures consisting of alternating films of epsilon-near-zero (ENZ) and dielectric material, and show that for such a stack it is possible to enha…
