WIP STUDY OF MULTIPLE METALLIC OBSTACLE SCATTERING

By N. Lucanu, I. Bogdan, and H. Baudrand

Full Article PDF (443 KB)

Abstract:
The Wave Iterative Process is applied and validated for the study of the scattering of a plane wave by a multiple metallic dipole diffraction structure. The case of a single metallic dipole is treated, at first in normal incidence, than arbitrarily placed with respect to the incident wave. A double dipole scattering structure is studied, mutual influence being taken into account. The diffraction system is further enlarged to 5 randomly placed dipoles, the results issued from the WIP study being compared with those given by the Moments Method. Finally, the possibility of taking into account a very large number of dipoles is examined, by introducing an equivalent dipole distribution. The influence of this approximation on the WIP precision is presented.
