Researchers have detailed the operational framework for meta-lens technology, focusing on the intricate design and optimization processes employed in their development. The methodology utilizes sophisticated computer simulations to model and refine lens structures. These simulations incorporate mathematical equations that define the boundaries and govern the electromagnetic behavior of light as it interacts with the lens. The design process involves iteratively adjusting material properties within the lens, often using materials like titanium dioxide and air, to achieve a desired focal point and numerical aperture. This optimization is achieved through algorithms that analyze and enhance the lens’s performance, ensuring it meets specific optical objectives. The researchers utilize techniques like finite element methods to discretize the models and Kreisselmeier–Steinhauser objective functions to target specific optical characteristics across a range of wavelengths. This approach offers a comprehensive and adaptable strategy for creating meta-lenses tailored for various advanced optical applications.
