Claim:
1. An electromagnetic energy filtering structure, comprising: an energy scattering layer, comprising the energy scattering layer being configured to have a first refractive index in a first-mode, and a second refractive index different from the first refractive index in a second mode when subjected to effects from an externally-applied electrical field, refractive indices of at least some of the plurality of substantially-transparent particles fixed in the substantially-transparent matrix material being modified by the externally-applied electrical field between the first mode and the second mode, and a refractive index of at least a portion of the substantially-transparent matrix material being modified by the externally-applied electrical field between the first mode and the second mode.
