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 decreasin...

可编程微丝复合材料：从功能单元到材料设计

微丝复合材料具有广泛的功能，可以通过磁场/应力刺激或杂交来积极地操纵它们。除了这些策略之外，在这里，我们将重点放在通过设计导线功能单元并将它们按特定布置组装来对微波响应进行编程。编程基于结构松弛和电磁阻尼定义的代码类型，以及基于波衰减，有效电导率和近场相互作用效应的代码模式。通过电流对导线进行退火可以实现结构松弛，这反映在居里温度，结构，磁和电性能的变化中。通过传输系数映射的波传播受导线浓度和周期性以及铸态和退火态导线在其阵列中的排列方式的控制。
