Microwave analog to light scattering measurements on a fully characterized complex aggregate
Résumé
We present experimental measurements of three-dimensional electromagnetic wave scattering in the microwave frequency range, by a complex aggregate consisting of 74 primary spheres with fully known optical and geometrical properties. We measured the complete amplitude scattering matrix or Jones matrix, from which the electric fields amplitude and phase with arbitrary polarization can be obtained. These results offer the opportunity to test approximate computational methods against experiments.
