AB Accurate modeling of electromagnetic propagation is crucial for the design andoptimization of integrated optical antennas, with applications in chip-to-fiber coupling,beam shaping, and free-space optical (FSO) communications. This work presents a 3Delectromagnetic propagator based on the angular spectrum method, capable of computingthe field evolution over both near-field and far-field regimes without paraxialapproximations.The proposed approach enables precise long-distance propagation, maintaining aintegral overlap with the analytical solution for Gaussian beams over distances up to tensof kilometers. Additionally, we provide simple analytical expressions to configuresimulation parameters, ensuring numerical accuracy and computational efficiency. The toolis validated through two case studies: (i) long-distance Gaussian beam propagation in freespace and (ii) near-field characterization of an integrated optical antenna for fiber coupling.The results confirm the versatility and accuracy of the proposed propagator for photonicapplications.
