Fabrication complexities

Definition

Fabrication complexities refer to the challenges and difficulties associated with the production of advanced materials and devices, particularly those with intricate structures and properties, such as metamaterials used in cloaking applications. These complexities arise from the need for precise control over material properties and the geometries involved, which can complicate the manufacturing processes and affect performance. The intricate designs required for effective cloaking often involve nanoscale features that demand advanced fabrication techniques.
