摘要
在保持精度的前提下改进了矩量法计算Vlasov辐射器近场分布的计算效率。将EFIE应用于Vlasov辐射器近场计算,并用快速多极子法对其加速。当波导模式为圆对称高次模时,Lagrange插值可以用于提高入射场的计算效率,与原始的计算方法比较,此方法精度基本不变,但计算激励时间的效率大大提高了。
The efficiency of calculating the near-field distribution of Vlasov radiator by Lagrange interpolation method was improved under the precondition of keeping the calculation accuracy. EFIE is used in the near-field calculation of Vlasov radiator, and accelerated with fast multipole method. When the waveguide mode is high-order circular symmetry mode,Lagrange interpolation can be used to improve the calculation efficiency of incident field. In comparison with the original calculation method,the accu-racy of this method is almost same,but the efficiency of calculating the stimulation time is extremely improved.
