Abstract :
The aim of this paper is to present Physical Optics - MultiLevel - Binary Space Partitioning (PO-ML-BSP) algorithm, which is suitable for calculating electromagnetic field levels in large scattering problems. This method combines a high frequency technique, Physical Optics (PO) approximation, with a space partition based on Binary Space Partitioning (BSP). In addition, Space Volumetric Partitioning (SVP) has been considered when the space is split into small geometrical domains (voxels) to create a multilevel scheme. The purpose is to reduce the computational cost of the analysis procedure. Monostatic radar cross section (RCS) of two spheres is compared for method of moments (MoM), PO-ML-BSP and PO-BSP (PO-ML-BSP without multilevel structure) results. Besides, coverage levels over a real scenario are calculated for PO-ML-BSP and PO-BSP configurations.
