一种分析复杂导体目标瞬态特性的快速方法

A Fast Approach to Transient Analysis of Complex Conducting Objects

将渐进波形估计技术引入到频域矩量法中,并结合傅立叶逆变换和自适应复频率跳跃技术,快速而准确地分析任意形状导体目标的瞬态特性,大大提高了计算效率。在分析中,脉冲波形和导体目标的几何形状可以任意。分别以理想导体方形平板、理想导体立方体、理想导体球体和理想导体锥体为例,并将计算结果与频域矩量法的结果进行了比较。它们之间良好的一致性说明了所提出方法的正确性和有效性。

A novel scheme is presented in the paper to fulfill the fast analysis and accurate modeling of transient characteristics of arbitrarily shaped conducting objects. The method is developed to greatly improve the computation efficiency by introducing the asymptotic waveform evaluation （AWE） in conjunction with implementing the inverse Fourier transform technique and the adaptively complex frequency hopping （CFH） technique. In the analysis, impulse waveform and the shape of the conducting objects are arbitrarily given. The perfectly conducting square plate, the perfectly conducting cube, the perfectly conducting sphere and the perfectly conducting cone are taken as examples, and the computed results are compared with those obtained by the Method of moments （MoM） in frequency domain. The agreement between them shows the correctness and effectiveness of the method proposed.
