基于各向异性介质波阻抗理论，提取了蜂窝结构等效电磁参数，分析了蜂窝倾斜角对蜂窝结构等效介电常数的影响。分析表明，在倾斜角较小时，横向等效介电常数近似为各向同性。等效介电常数张量元素随倾斜角度变化规律不同。对于无耗蜂窝，随着倾斜角度增大，横向等效介电常数增大，纵向等效介电常数减小，蜂窝谐振频率向低频移动。对于有耗蜂窝，介电常数变化规律与无耗蜂窝中类似。

Electromagnetic parameters of honeycomb structure are retrieved based on wave impedance theory. Tilt angle’s effect on equivalent permittivity of honeycomb structure is studied. It is found that the transverse electromagnetic parameters are effectively isotropic for smaller tilt angle .The components of the permittivity tensors change in different ways when tilt angle changes. For lossless honeycomb structure, the transverse permittivity increases while the z-direction permittivity decreases with the increase of tilt angle, result in lower resonance frequency. For lossy honeycomb structure, the variation trend of permittivity is similar to that of lossless honeycomb.
