This code has been used to generate the results presented in the paper entitled (DOI: 10.5194/ars-22-9-2024): "A numerical alternative for 3D addition theorems based on the bilinear form of the dyadic Green's function and the equivalence principle" authored by Giacomo Giannetti https://orcid.org/0000-0002-4318-8176 and Ludger Klinkenbusch.

The code is written in MATLAB. Text files contain the electric and magnetic fields exported from the full-wave simulator CST.

The package available at https://github.com/mingli-ai/FaVeST has been used for part of the code. The corresponding paper is: @article{FaVeST, title={FaVeST: Fast Vector Spherical Harmonic Transforms}, author={Le Gia, Quoc T. and Li, Ming and Wang, Yu Guang}, journal={ACM Transactions on Mathematical Software}, volume={47}, number={4}, pages={1--24}, year={2021}, publisher={ACM New York, NY} }
