| Abstract(in English) | In the case of optimizing antenna structure, the iterative calculations of electromagnetic field analysis are required. So far, in order to achieve the higher performance of impedance matrix calculations in the Method of Moment (MoM), an efficient calculation algorithm by using the Parallel Computers has been proposed. In this paper, 1) Conjugate Gradient (CG) Method which extended to complex, non-Hermitian symmetric matrix, and 2) COCG Method for iterative solvers are applied to realize the higher overall performance. In addition, improving the convergence of iterative methods with two techniques : 1) setting the threshold based on the accuracy of the input impedance and directivity, and 2) an initial guess by interpolating the current distributions based on the results for two adjacent frequencies are investigated. Also, three antennas : 1) helical antenna, 2) bowtie antenna, and 3) slot antenna were used in order to evaluate the validity of the two techniques. |
