  • Publication number: 20210218148
    Abstract: A multilayer thin film that reflects an omnidirectional structural color having a reflective core layer comprising a metallic material, a second layer extending across the reflective core layer, a third layer extending across the second layer, and an outer layer extending across the third layer. The multilayer thin film reflects a single narrow band of visible light that is less than 30° measured in Lab color space when viewed from angles between 0° and 45°, and the reflective core layer has a skin depth ? of greater than or equal to 1.0 ?m in a frequency range from 20-40 GHz, as calculated by: ? = 2 ? ? ( 2 ? ? ? ? f ) ? ( ? 0 ? ? r ) ? 5 ? 0 ? 3 ? ? ? r ? f , ? is skin depth in meters (m); ? is resistivity in ohm meter (?·m); f is frequency of an electromagnetic radiation in hertz (Hz); ?0 is permeability; and ?r is relative permeability of the metallic material.

  • Patent number: 10998638
    Abstract: A metallic component including NiCr and having a skin depth ? of greater than or equal to 1.0 ?m in a frequency range from 20-40 GHz, as calculated by: ? = 2 ? ? ? ( 2 ? ? ? ? ? f ) ? ( ? 0 ? ? r ) ? 503 ? ? ? ? r ? f . In this equation, ? is skin depth in meters (m); ? is resistivity in ohm meter (?·m); f is frequency of an electromagnetic radiation in hertz (Hz); ?0 is permeability; and ?r is relative permeability of the NiCr metallic material. The metallic component may be a discrete metallic particle or a layer in a multilayer thin film.
