Prior-knowledge Guided Machine-learning Enabled Metalens Antenna Design
Abstract – The design of antennas aims to meet the specific requirements of a system. This design relies on materials, fabrication processes, and design methodologies. Besides natural materials, we have introduced metamaterials—artificially engineered structures that exhibit unique electromagnetic properties not found in nature—to expand the boundaries of antenna design. Furthermore, we have explored new design methodologies to extend these boundaries.
Traditionally, antenna design begins with basic designs, which are then modified or optimized to meet the specifications. However, this approach has limitations in achieving optimal performance due to constrained degrees of freedom (DoF). These limitations arise from physical constraints such as volume restrictions and feeding structures, as well as restricted design space regarding the selection of viable structures or parameters in the design process. Therefore, deep learning algorithms are being utilized to significantly increase the degrees of freedom (DoF) in antenna design. This will expand the antenna design space and hold promise for enhancing antenna performance.
This talk will focus on outlining innovative approaches to antenna design. Specifically, it will explore the prior-knowledge-guided deep learning-enabled synthesis method and demonstrate its utility in enhancing the performance of metacells and metalens antennas.
