Physics-Informed Neural Networks with Architectural Physics Embedding for Large-Scale Wave Field Reconstruction

Researchers developed Physics-Embedded PINNs (PE-PINN) that achieve 10x faster convergence than standard physics-informed neural networks and orders of magnitude memory reduction compared to traditional methods for large-scale wave field reconstruction. The breakthrough enables high-fidelity electromagnetic wave modeling for wireless communications, sensing, and room acoustics applications.

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.
