1. A composition of matter useful for interacting with electromagnetic radiation, comprising:
one or more particles, wherein each of the one or more particles comprises a core and a metamaterial shell around the core, and wherein:
the metamaterial shell comprises structures having at least one dimension smaller than a wavelength of the electromagnetic radiation interacting with the one or more particles,
the structures each have a length and a width,
the length is along a direction extending from a surface of the core, and
the length is longer than the width so that an interaction of the electromagnetic radiation with the structures is anisotropic across the shell.
