Abstract Our numerical method of generating the boundary operator is based on conception of both analytical and discrete transparent boundary conditions . The elastic wave propagation in 2D orthotropic media is considered to show transparency of open circular boundary with proposed NRBC for all tested cases, even where PML approach fails.
