Tailor-Made Metasurface Camouflage
Abstract
Reducing electromagnetic scattering from an object has always been a task, inspiring efforts across disciplines such as materials science and electromagnetic theory. The pursuit of electromagnetic cloaking significantly advanced the field of metamaterials, yet achieving broadband, conformal cloaking for complex, non-trivial objects remains an unresolved challenge. Here, we introduce the concept of 'tailor-made metasurfaces' - machine-designed aperiodic structures optimized to suppress scattering from arbitrary objects by accounting for their layout, including resonant or large-scale features. Specifically, we demonstrated a wideband ~20% fractional bandwidth scattering suppression of more than 20-30 dB for various generic test objects, including randomly distributed wire meshes, spheres, and polygons. The demonstrated evolutionary optimization marks a leap forward in electromagnetic design, enabling the development of high-performance structures to meet complex technological demands.
