微带线在各向异性介质主轴旋转时的色散特性

Dispersion Characteristics of Microstrip Lines Under Principal Axes Rotation of Anisotropic Substrates

首次用时域有限差分法（ＦＤＴＤ）研究了在电和磁双各向异性介质中张量［ε］和［μ］的主轴同时旋转时，开式和屏蔽微带线的色散特性。结果表明，其传播特性与［ε］和［μ］的光轴偏差角有明显的关系。

In this paper, the FDTD method is first applying to analyze the dispersion properties of open and shielded microstrip lines whose substrate permittivity and permeabiliy tensors are rotated simultaneously. Results indicate that propagation properties can be considerably changed by the angle misalignment of [ε] and [μ] tensors.
