Abstract

 IN THIS PAPER WE INVESTIGATE NUMERICAL CHARACTERISTICS OF DIFFERENT FINITE-DIFFERENCE SCHEMES USED FOR 2D ACOUSTIC WAVE PROPAGATION SIMULATION. NUMERICAL DISPERSION IS ANALYZED AS A FUNCTION OF TEMPORAL FREQUENCY TO DEMONSTRATE DIRECTIONAL PROPAGATION DEPENDENCY OF DIFFERENT SCHEMES.5-POINT, 7-POINT AND 9-POINT EXPLICIT SCHEMES ARE COMPARED USING METRICS RELEVANT TO ACOUSTIC WAVE SIMULATION. IT IS SHOWN THAT THE 7-POINT HEXAGONAL SCHEME HAS BETTER ISOTROPIC CHARACTERISTICS THAN CONVENTIONAL 5-POINT AND 9-POINT RECTANGULAR SCHEMES.
