摘要
本文提出了一种新的入射场设置方法.采用一维FDTD算法来模拟入射波.所得结果与通常的入射场解析表达式的结果比较表明,采用一维FDTD算法引入的入射波在总场区分布均匀,在散射场区泄漏小.
In this paper, we present a new method for introducing incident wave into the FDTD region. We use the one dimensional FDTD algorithm instead of an analytical expression to produce the plane wave, so that the leakage of incident wave into the scattered field region is greatly suppressed and the homogeneity of incident field distribution in the total field region is improved.
