“…For example, in amorphous Co-rich ribbon coated with Co or Ni layers, the exchange coupling was much more obviously demonstrated in GMI profiles rather than hysteresis loops [19], similar to the case of Co 68.15 Fe 4.35 Si 12.5 B 15 glass-coated amorphous wire array [18]. Recently, the magnetostatic interactions among FINEMET ribbons or bistable microwires were studied using longitudinally driven magneto-impedance effect [24,25].…”

“…Lastly, changing the spacing between the wires has a significant effect on the transmission features of the arrays containing the same type of microwires (figures 8(d)-(f)) which is caused by the dynamic wire-wire interaction [31][32][33]. In this case, the dynamic magnetic interactions result mainly from the coupling with the electrical and magnetic component of incident waves rather than the magneto-static coupling, since 2 mm and 1 mm spacing are too wide to induce meaningful magneto-elastic energy [15,34].…”

Microwire composites possess a wide range of functionalities that can be actively manipulated by magnetic field/stress stimuli or hybridization. Beyond those strategies, here we focus on programming microwave response by designing the wire functional units and assembling them in a specific arrangement. The programming was based on a code type defined by structural relaxation and electromagnetic damping and on a code pattern by wave attenuation, effective conductivity and near-field interaction effects. Structural relaxation was achieved by current annealing the wires, which was reflected in changes in Curie temperature, structural, magnetic and electrical properties. The wave propagation mapped by the transmission coefficient was manipulated by the wire concentration and periodicity and by arrangement of as-cast and annealed wires in their array. Increasing the wire concentration blueshifted the transmission band of the wire composites due to larger conductivity, while decreasing the wire periodicity redshifted the band owing to stronger inter-wire coupling. A larger blueshift was obtained by alternating as-cast and annealed wires due to an overlapped flow closure of fields from the same type of wire in the array. Our strategy demonstrates that macroscopic properties of wire composites can be effectively programmed from a material structure/unit arrangement perspective. This concept promotes deeper understanding of high-frequency properties and further expands the applications of fiber-reinforced composites in fields such as information, energy and security technologies.
