Scattering properties: transmission S₂₁, reflection S₁₁ and absorption of the composites containing different combinations of as-cast A and annealed X (30 mA, B or 40 mA, C) randomly dispersed short-cut microwires in separated regions and different proportions, i.e., 33 pieces of as-cast and 17 pieces of annealed wires (right panel) and 17 as-cast and 33 annealed wires (left panel).
