Spatial coordinate transformations can be used to transform boundaries, material parameters or discrete lattices. We discuss fundamental constraints in regard to cloaking and review our corresponding experiments in optics, thermodynamics and mechanics. For example, we emphasize three-dimensional broadband visible-frequency carpet cloaking, transient thermal cloaking, three-dimensional omnidirectional macroscopic broadband cloaking for diffuse light throughout the entire visible range, cloaking for flexural waves in thin plates and three-dimensional elasto-static core-shell cloaking using pentamode mechanical metamaterials.
空间坐标变换可用于变换边界、材料参数或离散晶格。我们讨论了关于隐形的基本限制，并回顾了我们在光学、热力学和力学方面的相应实验。例如，我们着重介绍了三维宽带可见光频率地毯式隐形、瞬态热隐形、用于整个可见光范围内漫射光的三维全向宏观宽带隐形、薄板中弯曲波的隐形以及使用五模机械超材料的三维弹性静力学核壳隐形。
