Electrically controllable light modulator with a material composition based on embedded electro-optical media nanoparticles

is embedded a layer (10) of a material composition, a medium (2), on which is transparent in a range of electromagnetic radiation, and in which a single or a plurality of particles (3) which are arranged such that their frequency-dependent response to the irradiation of electromagnetic radiation of at least a resonance insbesndere a plasmon resonance, wherein the medium (2) comprises an inducible by an electric field, or variable refractive index anisotropy. generated by the two electrodes (20) electric field can shift the plasmon resonance and thus bring about an electrically controllable light modulation, in particular light scattering or reflection and absorption of light.
