Resumo

We demonstrate that the excitation of magnetic bulk plasmon-like resonances in A-near zero double-negative metamaterial slabs is suitable for the design of new sensing platforms, where light-to-plasmon coupling is reached without requiring a prism or grating coupler. This allows for excitation with light coming directly from the air and for dielectric substrates with any refractive index. In the microwave region this architecture is able to detect changes as small as 10(-2) in the refractive index of the superstrate. If the meta material slab is backed by a metallic substrate, on the other hand, the system can be used as a light-absorber for light harvesting applications. (C) 2018 Elsevier Ltd.
