(57) ABSTRACT A device includes a light adjustment apparatus having a first material and a
second material. The first material includes a first real dielectric permittivity and a positive
imaginary dielectric permittivity. The second material includes a sec ond real dielectric
permittivity and a negative imaginary dielectric permittivity. The first and second materials
affect the flow of light. The light adjustment apparatus includes a tunable material to enable
adjustment of the dielectric per mittivity of the respective materials.

A device includes a light adjustment apparatus having at least one material having a
dielectric permittivity, the at least one material to affect the flow of light, wherein the light
adjustment apparatus includes a tunable material to enable adjustment of the dielectric
permittivity of the at least one material.
