Compressing the memory variables in constant-Q viscoelastic wave propagation via an improved sum-of-exponentials approximation
Xu Guo, Shidong Jiang, Yunfeng Xiong +1
Earth introduces strong attenuation and dispersion to propagating waves. The time-fractional wave equation with very small fractional exponent, based on Kjartansson's constant-Q th…

An explicit multistep method for the Wigner problem
Yunfeng Xiong
An explicit multistep scheme is proposed for solving the initial-value Wigner problem. In this scheme, the integrated form of the Wigner equation is approximated by extrapolation o…
