Applications of the high performance computing in analyzing the electromagnetic scattering characteristics of targets

Abstract The electromagnetic numerical simulation based on high performance computing gains more and more attention in analyzing the electromagnetic scattering characteristics of targets to meet the engineering increasing requirements. Since each method has its own advantages and disadvantages, and there is no one method which can deal with all problems, it is necessary to develop multi approach for integrating the software system, which can provide efficient means to analyze the electromagnetic scattering characteristics of different targets. Considering scalability of algorithms and separability of physical characteristics, based on parallel adaptive structured/unstructured mesh applications infrastructure, several numerical methods are developed and integrated into the electromagnetic numerical simulation software system, JEMS, with studying computable modeling, interface design and modularized realization of algorithms. Some numerical examples illustrate JEMS has the capability in efficient solving the radar cross sections of different targets, and has advantages in large-scale parallel computing.
