|Abstract:||In this paper, the authors use the adaptive integral method (AIM) to simulate the electromagnetic scattering from large complex PEC objects. The first problem that we have investigated is the scattering from a dihedral corner reflector that may lead to a better understanding of scattering mechanisms and properties of more complex geometries. The second problem investigated is scattering from a multiplate structure consisting of trapezoidal plates. The third problem investigated is the scattering from a composite PEC sphere and plate structure. The AIM simulation results are compared to the results obtained using the physical optics (PO) technique. In order to test the capability of AIM further, an aircraft model with many patches of flat surfaces has been built for this purpose. The mesh generation and the measurement of the scattering pattern of the aircraft model have been carried out by us. With the mesh and measurement results of the aircraft model, the simulation was carried out using AIM. The numerical results for all the test cases show that the AIM is an efficient method for analyzing electromagnetic scattering from large complex PEC objects.|
