Optimisation du stockage du champ proche pour le calcul du champ lointain en FDTD
Résumé
A technique to compress the near-field data required to compute the radiated-field is proposed and evaluated. This technique is implemented in a FDTD code, and used to compute the radiated field by an array of printed antennas and an ultra wide band antenna. In those complex examples, a 97 % gain in memory storage is possible while maintaining good accuracy: less than 1 % error on the far-field radiation patterns.
