Simulation-Guided Investigation of Emergent Vacuum Response in Resonant Electromagnetic Systems

This paper presents a computational simulation framework for investigating phenomenological models involving emergent vacuum response, resonant pseudoscalar electrodynamics, asymmetric electromagnetic topology, and residual-force hypotheses in resonant electromagnetic systems. Rather than claiming verified new physics, the work develops a falsifiable numerical methodology designed to test whether proposed emergent-field equations remain internally self-consistent, numerically stable, experimentally distinguishable from conventional electrodynamics, and capable of producing measurable resonant signatures under controlled conditions. The framework combines finite-difference time-domain (FDTD) concepts, effective-field modeling, resonant cavity analysis, null-test methodology, and a normalized proof-of-concept toy simulation demonstrating stable resonance buildup, delayed ringdown, damping-dependent relaxation, and bounded energy evolution. The work is intended as a low-cost computational pathway for evaluating speculative vacuum-response models prior to expensive laboratory experimentation.
