| 1. A negative index material, comprising:
a plurality of unit cells, each unit cell comprising a resonator formed on a substrate, wherein the resonator exhibits a negative
permeability and a negative permittivity over a frequency band of interest; and
a three-dimensional volume including a bulk solution wherein the plurality of unit cells is disposed in the bulk solution
to form a substantially random pattern of unit cells to produce a negative effective permeability and a negative effective
permittivity over the frequency band of interest for the three-dimensional volume.
