Abstract
An electromagnetic wave resonator comprising a body, wherein the body: has a structure extending essentially in a plane (r, θ), comprises a material in a region between limit radii rand r, where 0≦r<rand rcorresponds to a radius of a convex hull () of the structure; and allows for electromagnetic wave propagation, and wherein an effective refractive index n(r), as obtained from angularly averaging a refractive index of the material in the plane (r, θ), decreases within said region.
