arXiv:2605.20514v1 Announce Type: new Abstract: We introduce FLASH-MAX, a shallow, exact-by-construction neural network architecture for predicting homogeneous electromagnetic fields from sparse pointwise observations. Each hidden neuron represents a separate exact solution to Maxwell's equations, so that the network satisfies the governing equations symbolically by construction and can be trained end-to-end from sparse data within seconds. We prove a universal approximation result showing that this exact model class remains universal on arbitrary domains. FLASH-MAX reaches sub-1% relative val
The development of FLASH-MAX signifies a continuous drive for more efficient and accurate AI models, especially those rooted in explicit physical laws, reflecting a growing trend in scientific machine learning.
This development allows for extremely rapid and accurate simulation of complex electromagnetic fields, which is critical for advances in chip design, materials science, and various engineering applications.
Traditional computational methods for Maxwell dynamics could be significantly accelerated and made more robust, enabling quicker iteration and optimization in design processes where electromagnetism is a core component.
