A Parallel Implementation for the Time-Domain Analysis of a Rectangular Reflector Antenna Using OpenMP
Keywords:
Electromagnetic scattering, parallel computing, rectangular reflector, time domainAbstract
This paper presents and evaluates a parallel time domain analysis of a rectangular reflector on multicores machine. Rectangular reflector antennas have motivated the time-domain analysis of electromagnetic scattering problems. The asymptotic time domain physical-optics (TDPO) is applied to the analysis of a rectangular reflector illuminated by a Gaussian-impulse. It is a numerical technique used in computational electrodynamics. The effects of time-delayed mutual coupling between points on the surface will be ignored to avoid the numerical limitations found in other conventional time-domain techniques such as interpolation error, numerical dispersion error, etc. As a result, the scattered signals at the specular reflection point, at the edges, and at the corners can be clearly distinguished. Furthermore, this paper evaluates and compares the performance of the sequential time-domain analysis against the parallel time-domain analysis on multicores machine.
