Verify the numerical precision of the AN-SOF engine through this detailed validation study of cylindrical dipoles. By testing the principle of energy conservation, comparing input resistance against far-field radiation resistance, we demonstrate a near-perfect correlation with errors below 0.035%.

Examine the numerical stability of cylindrical dipole modeling through this rigorous convergence study. By analyzing input impedance as a function of discretization density and length-to-radius ratios, this article demonstrates how AN-SOF overcomes the traditional divergence issues found in many MoM codes, such as NEC-2. While older engines often fail to provide convergent reactance values when using a delta-gap source with fine segments, AN-SOF's exact kernel ensures monotonic stability. Validation against the classical 73.1 + j 42.5 Ohm half-wave dipole thin-wire limit and convergence analysis confirm the engine's precision for both resonant and anti-resonant linear antennas.
