A Physics-Informed Hierarchical Neural Network for Microwave Scattering Analysis of 3D PEC Targets
arXiv:2508.03774v5 Announce Type: replace Abstract: Accurate modeling of scattering from three-dimensional (3D) perfectly electrically conducting (PEC) targets at microwave frequencies constitutes a fundamental objective in computational electromagnetics, particularly for radar cross section (RCS) prediction and microwave scattering analysis. Classical solvers, such as the method of moments and the Multilevel Fast Multipole Algorithm (MLFMA), although provide high physical fidelity, they become costly under scenarios of repeated queries involving many incidence configurations or frequencies, w
The increasing computational demands of complex electromagnetic simulations are pushing researchers towards AI/ML solutions to overcome the limitations of classical physics solvers.
This development can significantly enhance the efficiency and accuracy of crucial defense and engineering applications, especially where rapid and repeated scattering analysis is required.
AI-driven methods are becoming a viable alternative to traditional computational electromagnetics, potentially accelerating design cycles and operational analysis for complex 3D targets.
