1. An omnidirectional structural color multilayer structure comprising:
a core layer;
a dielectric layer extending across the core layer; and
a tungsten absorber layer extending across the dielectric layer with an interface therebetween,
wherein the multilayer structure has a single narrow reflection band of less than 400 nanometers when viewed from angles between 0 and 45 degrees, and
the interface between the dielectric layer and the tungsten absorber layer has a near-zero electric field at a first incident electromagnetic wavelength and a large electric field at a second incident electromagnetic wavelength, the second incident electromagnetic wavelength not equal to the first incident electromagnetic wavelength.
