Abstract

Based on the full-wave electromagnetic simulation and the principle of near-field diagnostics, the near-field scattering characteristics of typical scatterers illuminated by vortex electromagnetic waves are studied. It’s shown from the simulation data that the ability of identification of scatterer characteristics by vortex electromagnetic wave is higher. In addition to the amplitude and phase patterns, the orbital angular momentum (OAM) modal spectrum patterns of the scattering field also carry the information of the geometric shape and material characteristics. The application of OAM modal spectrum patterns will help to improve the ability of information acquisition and target detection of electromagnetic wave.
