Since the first observation of Airy beam in 2007, its propagation properties, such as self-acceleration, self-healing and reflection/refraction, have been studied widely [1, 2]. Based on these achievemnts, with the development of photonic lattices, the studies of Airy beam have been spread from homogeneous meduim to periodic structures. In photonic lattices, researchers demonstrate that the accelerating...
Based on the strong ground motion data recorded at Zigong array during Wenchuan Earthquake on May 12, 2008, the characteristics of peak ground acceleration (PGA) and response spectrum are analyzed. The results indicate that the mountain topography greatly influences the seismic wave propagations. The horizontal PGA increases more greatly than the vertical PGA with increasing elevation of the mountain;...
