| The electromagnetic (EM) scattering characteristics of large-scale complex objects have been intensely studied by many researchers in the past. Compared to traditional experimental method, computational electromagnetic techniques are very efficient method to solve the EM scattering problem from large-scale complex bodies. In this paper, the applied microwave electronic design automation (EDA) software has been developed to analyze the electromagnetic scattering of complex metallic targets. Two efficient algorithms, the multi-level fast multipole algorithm (MLFMA) and the physical optics method (PO), are integrated into the software. The MLFMA method is used to analysis the electromagnetic scattering from electronic large metallic objects, while the PO method is the high frequency approximate technique for solving super large-scale objects.Some tool software such as Visual C++ 6.0 and OpenGL are applied to develop the microwave EDA software. All the source codes are programmed based on Visual C++ and Compaq Visual Fortran language. To verify the validity of the EDA software, some typical objects are analyzed. Numerical results are given to demonstrate the accuracy and efficiency of the applied microwave EDA software. |
