Abstract

Computations of the variation with groove depth of the SAW scattering properties of a uniform shallow-grooved reflector array are reported for an equivalent isotropic elastic substrate representing Y-cut Z-propagating LiNbO₃. In agreement with previous qualitative conclusions based on experimental studies of SAW grooved resonators, the present computations indicate the existence of an optimum groove depth yielding maximum array SAW reflectivity. This optimum groove depth is a monotonically decreasing function of the total number N of grooves in the array. Computed optimum groove depths for various fixed values of N are presented.
