Abstract
The evolution of electromagnetic (EM) systems, ranging from advanced electronic integration to smart wireless environments, demands a new paradigm in modeling and simulation. This lecture presents a problem-driven exploration of computational electromagnetics, grounded in wave physics and guided toward the frontier of machine intelligence.
We begin with the challenge of scale. As EM systems grow in size and complexity, classical full-wave solvers face fundamental bottlenecks. We introduce domain decomposition strategies that offer both algorithmic scalability and computational modularity. These methods enable system-level simulation with component-level resolution. Next, we address the prediction challenge in chaotic and confined EM environments, where wave solutions exhibit extreme sensitivity to boundary conditions and material variations. Here, we turn to the stochastic Green’s function: a statistical, physics-based surrogate that captures the intricate interplay of coherence and randomness, rooted in wave chaos physics and the mathematics of random matrices. The final part of the talk explores the frontier of machine intelligence. We will discuss photon splatting and neural operators for real-time EM wave propagation, as well as quantum-based optimization techniques for inverse design and control of intelligent surfaces.
