Abstract

Parallel computation technique is an effective way to solve large-scale electromagnetic problems. This paper writes the program of parallel FDTD based on the JASMIN framework. The parallel FDTD program was used for simulating the time-domain far field property of the electric dipole source and a single TEM horn antenna. Numerical results show that the program is correct and efficient. Two large-scale arrays of TEM horn antenna were simulated. Their near-field and far-field results were given. The two examples provide a solution for studying large-scale antenna array and show that the program has the ability to solve large-scale electromagnetic problems.
