Cross-Validated Numerical Predictions of Electromagnetic Stress Asymmetry in Asymmetric Resonant Cavities

This work presents a cross-validated numerical investigation of electromagnetic stress asymmetry in asymmetric resonant cavity systems. Using reduced-order finite-difference time-domain (FDTD) and finite-element-inspired (FEM) computational approaches, the study evaluates field-energy distributions, asymmetry parameters, convergence behavior, and effective force scaling under resonant conditions. Multiple validation layers are included, including mesh-convergence testing, cross-method comparison, residual analysis, and control configurations. The results demonstrate consistent asymmetry-dependent scaling across independent computational approaches, with bounded residuals and no systematic bias across parameter…
