Abstraction: AI inverse design produces unintuitive but high-performance RF chips

Key points:

Princeton and IIT Madras researchers used convolutional neural networks for "inverse design" of RF/sub-terahertz circuits, starting from desired properties and working backward to geometry
AI-generated circuits have randomly-shaped, unintuitive structures that humans cannot understand but that outperform classical designs
Synthesized filters with precise band-pass characteristics in minutes vs. days/weeks using traditional methods
Published in Nature Communications (DOI: 10.1038/s41467-024-54178-1); nearly $10M NSTC grant awarded to Princeton for follow-on work
Black-box nature raises reliability and safety concerns for critical applications like medical devices or autonomous vehicles
Lead researcher Kaushik Sengupta frames the goal as enhancing human productivity, not replacing designers
