Finite-Element Analysis of Resonant Electromagnetic Stress Redistribution in Asymmetric Cavities

This paper develops a computational electrodynamics framework for analyzing electromagnetic stress redistribution, field localization, and conservation-compatible momentum bookkeeping within asymmetric resonant cavity systems. Using finite-element and finite-difference simulation concepts, the work explores Maxwell stress tensors, resonant mode structure, ringdown dynamics, environmental boundary sensitivity, and nonequilibrium field organization under constrained phenomenological assumptions. Emphasis is placed on conservation closure, center-of-mass consistency, numerical stability, and artifact discrimination rather than claims of reactionless propulsion or experimentally verified anomalous forces. The paper argues that even null simulation outcomes provide valuable constraints on speculative nonequilibrium electrodynamic response models while establishing a structured computational foundation for future precision cavity studies.
