[IEEE AP-S/MTT-S Seminar] Prior Knowledge-Guided, Deep Learning-Enabled Generative Metantenna Design
Please join us for an upcoming seminar by Dr. Zhi Ning Chen, Professor at the National University of Singapore.
Date: Monday, 21 July 2025
Time: 3 – 4 pm (ET)
Location: University of Toronto, Room BA 2135, Bahen Centre for Information Technology, 40 St George St, Toronto, M5S 2E4
Abstract:
The rapid evolution of wireless technologies continues to drive the demand for increasingly advanced antenna solutions. Simultaneously, breakthroughs in artificial intelligence (AI)—particularly in generative neural network methodologies—are opening new frontiers in antenna design innovation.
This talk begins with a brief overview of the challenges involved in high-performance antenna design, emphasizing the need to explore broader design spaces to increase degrees of freedom and uncover novel solutions. To address the resulting complexity, transformative deep learning (DL) models—a subset of machine learning (ML) within AI—are introduced as tools for generative synthesis in antenna design.
Three design exemplars utilizing generative adversarial networks (GANs) are presented, demonstrating innovative approaches to metacell design within metasurfaces. These are achieved through pixelization strategies and DL-driven algorithms. A particular focus is placed on the integration of prior knowledge (PK) into the DL-based synthesis process, illustrating its effectiveness in generating metacells for metalens applications.
The presentation further highlights how metalenses synthesized using PK-guided DL methods exhibit breakthrough performance and offer enhanced functionalities in metalens antenna design. The talk concludes with a forward-looking perspective on the integration of AI and antenna engineering, outlining its transformative potential and the emerging challenges and opportunities in this evolving interdisciplinary domain.
