Abstract

Nonlocality is typically studied in simplified 2D or symmetric 3D structures and the ability to perform nonlocal simulations for complex 3D structures is lacking. Here the authors examine non-local optical effects in small gaps and its effect on the optical response of a coaxial metamaterial in the mid-IR.
