“…The finite‐difference method (FDM) is most popular (Alford et al ., 1974; Lisitsa et al ., 2010; Zhang & Chen, 2010; Virieux et al ., 2011; Lan et al ., 2015). Due to programming simplicity and low storage capacity, FDM has been widely used in numerical modelling (Wang & Liu, 2007; Liu & Sen, 2009; Lisitsa & Vishnevskiy, 2010; Lisitsa et al ., 2012), reverse time migration (Herrmann & Li, 2012; Zhao & Sen, 2019) and inversion problem (Ren & Liu, 2015).…”
