The propagation and transfotmation of GLB in a homogeneousmedium is discussed.
讨论了类高斯光束在均匀介质中的传播。
2
Finite Element Technique based on Rayleigh-Ritz idea is used to solve wave propagation in non-homogeneousmedium with variable velocities.
为求解变速不均匀介质中波的传播问题，使用了利用瑞雷-里兹法的有限元技术。
3
Then the displacement field in homogeneousmedium is considered the result of the first iteration, and the displacement field is solved by this integral equation.
