Electromagnetic complex scattering for a sphere and a conducting plank in K-wave band

The electromagnetic interaction between a target and a conducting plank is investigated utilizing the electromagnetic images method. The complex scattering Held is presented. The scattering cross section in which the electromagnetic interaction has been included is also educed and the simulation is consistent to experiment. Results show that in a definite distance the electromagnetic interaction is least in the medium wave band. In K- wave band, the error induced by the electromagnetic mutual effect between a large scale target and the conducting plank arrive to 20~30%. Comparing with the change versus frequency, the target size affects the complex scattering distinctively, which presents a theoretical reference for electric system design and electromagnetic compatibility.
