| contents | Full-space electromagnetic invisibility mainly includes light-bending and scattering-cancellation cloaking. Light-bending cloaking causes double-blind phenomenon and is incompatible with sensing, while scattering-cancellation cloaking allows signal interaction and is more suitable for sensors and communication systems. However, traditional scattering-cancellation cloaking depends highly on target shape and size, making it difficult to realize cloaking for irregular, inhomogeneous and electrically large objects. To solve these problems, this work proposes an electromagnetic invisibility gene injection strategy inspired by biological camouflage. Objects are decomposed into subwavelength units, and customized invisibility genes are injected into each unit according to electromagnetic parameters to achieve overall scattering cancellation. Simulations and microwave experiments verify that this method can realize efficient cloaking for objects with arbitrary shapes, dielectric constants from 2 to 10, and different unit morphologies. This strategy breaks the limits of traditional cloaking and provides a universal, flexible scheme for practical applications such as antenna supports and electromagnetic transparent covers. |
