“Fata Morgana” or “Mirage” phenomena have long been captivated as optical illusions, which actually relies on gradient‐density air or vapor. Man‐made optical illusions have witnessed significant progress by resorting to artificially structured metamaterials. Nevertheless, two long‐standing challenges remain formidable: first, exotic parameters (negative or less than unity) become inevitable; second, the signature of original object is altered to that of a virtual counterpart. It is thus not able to address the holy grail of illusion per se, since a single virtual object still exposes the location. In this study, those problems are successfully addressed in a particular setup—illusion thermotics, which identically mimics the exterior thermal behavior of an equivalent reference and splits the interior original heat source into many virtual signatures. A general paradigm to design thermal illusion metadevices is proposed to manipulate thermal conduction, and empower robust simultaneous functions of moving, shaping, rotating, and splitting heat sources of arbitrary cross sections. The temperature profile inside the thermal metadevice can mislead the awareness of the real location, shape, size, and number of the actual heat sources. The present concept may trigger unprecedented development in other physical fields to realize multiple functionalized illusions in optics, electromagnetics, etc.

幻觉热学

长期以来,“ Fata Morgana”或“ Mirage”现象被视为幻觉,而视错觉实际上依赖于梯度密度的空气或蒸气。人造光学错觉已通过诉诸于人工构造的超材料而取得了长足的进步。尽管如此,仍然存在两个长期挑战:第一,外来参数(负数或小于一)成为必然。第二,将原始对象的签名更改为虚拟副本的签名。由于单个虚拟对象仍然暴露该位置,因此它本身无法解决幻觉的圣杯。在这项研究中,这些问题已通过特定的设置成功解决,例如幻觉热学,模仿相同参考的外部热行为,并将内部原始热源分成许多虚拟特征。提出了一种设计热错觉元设备的一般范例,以操纵热传导,并实现任意截面的热源的移动,成形,旋转和分离的强大同时功能。热元设备内部的温度曲线可能会误导人们对实际热源的实际位置,形状,大小和数量的认识。本概念可能会触发其他物理领域的空前发展,以实现光学,电磁等方面的多种功能化幻觉。并具有强大的同时移动,成形,旋转和分割任意截面热源的强大功能。热元设备内部的温度曲线可能会误导人们对实际热源的实际位置,形状,大小和数量的认识。本概念可能会触发其他物理领域的空前发展,以实现光学,电磁等方面的多种功能化幻觉。并具有强大的同时移动,成形,旋转和分割任意截面热源的强大功能。热元设备内部的温度曲线可能会误导人们对实际热源的实际位置,形状,大小和数量的认识。本概念可能会触发其他物理领域的空前发展,以实现光学,电磁等方面的多种功能化幻觉。
