Patent ID: 8865797

Claim:
A composite material comprising: an embedding medium; and a core-shell composite particle suspended in the embedding medium, wherein the composite material displays at least 90% transmittance of incident electromagnetic radiation, and wherein the core-shell composite particle comprises a core material having a first refractive index and a shell material having a second refractive index different from the first refractive index, wherein the core-shell composite particle has an effective refractive index within five percent of a refractive index of the targeted embedding medium, and the effective refractive index of the particle will have a value between the first refractive index and the second refractive index, wherein upon suspension of the core-shell composite particle in the embedding medium to form a matrix, the matrix displays a reduced scattering cross-section of incident electromagnetic radiation compared to a matrix wherein the effective refractive index of the core-shell composite particle is greater than five percent of the refractive index of the embedding medium.
