Abstract: The present invention provides a magnetic multilayer pigment flake and a magnetic coating composition that are relatively safe for human health and the environment. The pigment flake includes one or more magnetic layers of a magnetic alloy and one or more dielectric layers of a dielectric material. The magnetic alloy is an iron-chromium alloy or an iron-chromium-aluminum alloy, having a substantially nickel-free composition. The coating composition includes a plurality of the pigment flakes disposed in a binder medium.

Abstract: In some implementations, a metamaterial absorber (MMA) is configured to absorb a particular range of electromagnetic radiation. The MMA includes a first metal or semiconductor material; a dielectric material disposed on the first metal or semiconductor material; and a second metal material disposed on the dielectric material. A length dimension associated with the MMA is less than or equal to 200 micrometers (μm), a width dimension associated with the MMA is less than or equal to 200 μm, and a thickness dimension associated with the MMA is less than or equal to 8 μm.

Abstract: A method of providing a configuration of a system of interference filters with a visible color shifting effect, includes: a hue matching step of identifying a configuration of a first interference filter including two first metal layers and a first spacer layer therebetween, and a configuration of a second interference filter including two second metal layers and a second spacer layer therebetween, wherein the first and second filters match in hue at the first viewing angle, and the mismatch in hue at the second angle; and a lightness adjustment step which may include modifying the layer material or the layer thickness of one of the metal layers; wherein a difference in lightness at the first viewing angle between the first and second modified filters is less that a difference in lightness at the first viewing angle between the first and second filters.
