Fully-analog array signal processor using 3D aperture engineering

Researchers developed a fully-analog array signal processor (FASP) using 3D aperture engineering with cascaded metasurface layers that achieves N times higher angular resolution than the Rayleigh diffraction limit. The system can perform super-resolution direction-of-arrival estimation and multi-channel source separation, demonstrating 20 dB radar jamming suppression and 13.5x communication capacity enhancement at 36-41 GHz frequencies.

The False Promise of Zero-Shot Super-Resolution in Machine-Learned Operators

Research reveals that machine-learned operators (MLOs) fail at zero-shot super-resolution, unable to accurately perform inference at resolutions different from their training data. The study identifies key limitations in frequency extrapolation and resolution interpolation, proposing a multi-resolution training protocol as a solution.

Physics-Consistent Diffusion for Efficient Fluid Super-Resolution via Multiscale Residual Correction

Researchers developed ReMD, a physics-consistent diffusion framework that improves fluid super-resolution by incorporating physical constraints and multiscale modeling. The approach addresses limitations of existing image and diffusion models when applied to fluid dynamics, achieving better accuracy and spectral fidelity with fewer sampling steps.
