The results show that whether the stiffness profiles are smoothly varying or layered, the fundamental mode dominates the surface wave field and the effective phase velocity approaches to the phase velocity of the mode in far field for the regular profiles. For the irregular profiles, the higher modes have a significant influence on the surface wave field. The intensity and the frequency range of the influence are related to variation of the profile stiffness.

结果显示，无论剖面刚度是缓变还是分层变化，对规则剖面，表面波场基阶模态占主导地位，远场表面波有效相速度与基阶模态相速度接近；对不规则剖面，表面波场中高阶模态影响较大，影响程度及频率范围与剖面刚度变化有关。

Then we in-vest gate Seiberg-Witten map, which defines the equivalence relation of the gauge symmetries in different spaces. We also analyse the U gauge electromagnetic field in noncommutative space.
