摘要： A discrete metallic particle having a metallic material, and a coating covering at least a portion of the metallic component. The discrete metallic particle has a thickness from 50 nm to 1000 nm, and the discrete metallic particle has a skin depth δ of greater than or equal to 1.0 μm in a frequency range from 20-40 GHz. The skin depth δ is calculated by:

摘要： A system and method are provided for forming electromagnetic energy transmissive layers, which are particularly configured to selectively scatter specific and selectable wavelengths of electromagnetic energy, while allowing remaining wavelengths to pass therethrough. Processes are provided by which to form, or otherwise incorporate, one or more energy scattering layers, including uniquely implementing optical light scattering techniques in such energy scattering layers, and to objects, object portions, wall plates, lenses, filters, screens and the like that are formed of, or that otherwise incorporate, such transmissive energy-scattering layers. Refractive indices of particles fixed in a matrix are tunable in order that the finished layers provide an opaque appearance when viewed from an energy-incident excited by light in the visible spectrum. A color, pattern, texture or image of the scattering layer may be rendered according to an individual user's desires, the layers being substantially-transparent to light passing through layers.

摘要： A display window and a vehicle are provided. The display window includes window glass and at least one projection device. The at least one projection device is configured to generate at least one beam of projection light, and correspondingly project the at least one beam of projection light onto at least one projection region of the window glass to correspondingly form at least one projection image. At least 90% of each of the at least one beam of projection light is S-polarized light. The at least one beam of projection light includes first projection light. The at least one projection region includes a first projection region. The first projection region has a first reflectivity of at least 25% for the first projection light projected at the first angle of incidence.
