摘要: 本文通過(guò)多項(xiàng)式近似導(dǎo)出了一種可變網(wǎng)格的時(shí)域有限差分算法,其空間網(wǎng)格的大小能沿任意軸向變化,而且具有高階離散精度,從而節(jié)省了機(jī)時(shí),提高了計(jì)算精度。并首次應(yīng)用于高速集成傳輸線(xiàn)變角度拐角的全波分析。本方法簡(jiǎn)化了以往方法的分析過(guò)程,其結(jié)果與有關(guān)文獻(xiàn)相一致,從而驗(yàn)證了算法的可靠性和有效性。

Abstract: A new time domain finite difference method with variable grids of high accuracy is derived by the polynomial approximation, and applied to analyze the variable-angle transmission line discontinuities. The method has the advantages of comparatively less memory space and CPU time, and is much simpler than other techniques. Test results are in good agreement with published data, thereby the accuracy of the new method is verified. -
