The results indicate that a half-wave dipole array has good performance when array element space is also half-wave.
结果表明，对于半波长的偶极子阵列，当阵元间距为半波长时性能达到最佳。

In this paper, a finite element method with lumped mass formulation is applied to analyse the transient SH wave propagation in an elastic half-space with a dipping layer.
A 1d finite element method in time domain is developed, where the wave motion of free field in elastic half-space by SH wave oblique incidence is simulated.
