Abstract
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: Where δ is skin depth in meters (m); ρ is resistivity in ohm meter (Ω·m); f is frequency of an electromagnetic radiation in hertz (Hz); μis permeability; and μis relative permeability of the metallic material.
