Fabrication limitations

Definition

Fabrication limitations refer to the constraints and challenges encountered during the manufacturing process of materials and structures, particularly when it comes to creating intricate designs at micro and nanoscale levels. These limitations can impact the performance and effectiveness of terahertz metamaterials and artificial structures, as they determine what can realistically be produced in terms of size, shape, material properties, and uniformity. Understanding these constraints is crucial for optimizing design and ensuring functionality in applications across various fields, including telecommunications and imaging technologies.
