摘要：

针对等腰直角三角形平面模型效率低和精度差的问题，在双频点近似算法的基础上，提出了一种快速的Spice兼容等腰直角三角形平面谐振腔模型．与电感近似的等腰直角三角形平面模型相比，提出的模型使用最少的谐振腔基本模式与单节的高阶修正电路，不仅提高了等腰直角三角形电源地平面的仿真效率，而且改善了模型精度．仿真结果表明，电感近似模型在分类关键因子为2时，最大误差约为10％；提出的模型在分类关键因子为1.3时，最大误差约为1％，其仿真时间仅为电感近似模型的26％，验证了该模型在提高等腰直角三角形电源地平面的仿真效率和改善模型精度上的有效性．

Abstract:

For the low efficiency and poor accuracy of the model for isosceles right-angled triangular planes, a fast Spice-compatible resonant cavity model is proposed based on double frequencies approximation. Compared with the model based on the inductance approximation, the proposed method greatly improves the simulation efficiency and accuracy of isosceles right-angled triangular power and ground planes, since it uses the least number of basic modes and a high-order modified circuit. Simulation results indicate that the error of the inductance-based model is about 10％ when the critical factor of categorization equals 2, while the error of the proposed model is about 1％ when the critical factor of categorization equals 1.3. And the simulation time of the proposed model is only 26％ that of the inductance-based model. This verifies the effectiveness of the proposed model in improving the simulation efficiency and accuracy of isosceles right-angled triangular power and ground planes.
