摘　　要：借助于铝合金板和聚氯乙烯发泡板交错排列的双物理场零空间介质,设计得到一种可同时分束横向磁极化的电磁波(TM平面波)和热流的电磁-热分束器。数值模拟结果与实验结果均验证了该分束器的双物理场分束效果,并且通过调整两种材料板的数目还可以实现对分束比的调控。这为双场检测、高集成度片上系统、电子设备等需要同时考虑电磁和热管理的场合提供了一种新的电磁-热调控方法。Objective In transformation optics and transformation thermodynamics,many structures capable of regulating a single physical field have been proposed,such as electromagnetic/thermal cloaking structures,electromagnetic/thermal focusing structures,electromagnetic/thermal beam expansion structures,electromagnetic/thermal bending structures,and electromagnetic/thermal beam splitting structures.Among these structures,beam/field splitting structures can divide an incident wave into two or more outgoing waves.For instance,electromagnetic wave splitters can divide an incident wave into two or more outgoing waves,which can be employed for power distribution,power tracking,and electromagnetic signal routing.Thermal flux splitters can divide the incident heat flux into two or more outgoing heat fluxes and play a key role in fields such as thermal management,energysaving technology,and thermal sensing,thus providing new pathways and solutions for heat flux control and utilization.With the continuous improvement in onchip system integration,there is an increasing demand for yielding splitting effects for both electromagnetic waves and heat fluxes by a single structure.However,to date,there is still no structure that is effective for both electromagnetic waves and heat fluxes simultaneously.Meanwhile,the design of structures using transformation optics and transformation thermodynamics is always complex with precise requirements for the materials of the structure,which increases the implementation difficulty.To this end,we design an electromagnetic‒thermal splitter that can simultaneously split transverse magnetic(TM)polarized electromagnetic waves and heat fluxes by staggered aluminum plates and expanded polystyrene boards.Additionally,both numerical simulations and experimental results have verified the doublephysicalfield splitting effect of the proposed electromagnetic‒thermal splitter.By adjusting the arrangement of the two materials,a tunable splitting ratio can be achieved.Finally,we provide a new method for electro
