基于电磁弹性线性理论，分析了弹性波在扇形截面多铁圆柱波导中的传播。采用波势法解析导出特征方程，得到色散关系。通过分析全色散谱的实支、虚支和复支来研究波的基本特性。研究发现，相位速度和截止频率在很大程度上取决于波导的角度尺寸，这是控制特定材料多铁性波导色散特性的重要因素。此外，还提出了一个双层模型与单层模型进行比较。
The propagation of elastic waves in multiferroic cylindrical waveguides of sectorial cross-section is analyzed based on the linear theory of electro-magneto-elasticity. A wave potential method is adopted to derive analytically the characteristic equations, from which the dispersion relations are readily obtained. Representative examples are performed to investigate the essential characteristics of the waves by looking into the real, imaginary and complex branches of full dispersion spectra. It is found that phase velocities and cutoff frequencies depend considerably on the waveguide’s angular measure, which should be a significant factor to control the dispersion characteristics of the multiferroic waveguide of specific materials. Furthermore, a two-layer model is also presented to compare with the single model.
