Their resonance frequencies of the fundamental Lame mode were examined to confirm the validity of the SGCV models of the free surfaces. The resonance frequency obtained with an SGCV, which uses bipolynomial interpolation with values of velocity on six adjoining grids to evaluate the derivatives of velocity vector fields on a grid, showed good agreement with the analytical resonance frequency.}, title = {Implementation of Free-Surface Condition for Finite-Difference Time-Domain Method Using a Staggered Grid with the Collocated Grid Points of Velocities}, volume = {52}, year = {2013} }
