Abstract
A modulator in an imaging apparatus includes a metamaterial shell surrounding an opaque core. The metamaterial is tunable, so that the metamaterial acts as a waveguide for light at a given wavelength. This property of the metamaterial is used to modulate the light beam in an imaging apparatus. The light beam can be guided around the opaque core under a first voltage condition, or the light beam can be blocked by the opaque core under a second voltage condition.
