The characteristics of wave propagation in laminated grid structure are analyzed using the lumped-mass method to yield the phase constant surface. The directions and regions of wave propagation in this grid structure for certain frequencies during pass bands are predicted with the iso-frequency contour lines of the phase constant surface, which are also validated with the calculated harmonic responses of a finite two-dimensional grid structure with 15×15 unit cells.
