A systematic numerical framework based on Integral Equations and Generalized Sheet Transition Conditions (IE-GSTCs) is presented in 2D to synthesize closed metasurface holograms and skins for creating electromagnetic illusions of specified objects and as a special case. to camouflaging them against their backgrounds. The versatile hologram surface is modeled using a zero-thickness she... https://theplayfulcollectivees.shop/product-category/bicycles/
