Abstract:

In this paper the efficient numerical methods for EM scattering from low observation targets have been introduced. These methods based on MLFMA and included some further improvements, among which the JMCFIE for surface integral equation of homogeneous dielectric scattering, the multi-TDS boundary conditions for volume integral equation of multi-layered dielectric scattering and their applications have been discussed in detail. Finally, the code, called as Parallelized Universal Electromagnetic Scattering Tool (P-UEST) and developed by our group for modeling of scattering from the stealth airplane, has been described. Some application examples have also been given in this paper.
