To build a better stimulator display for the human tactile system, it is necessary to quantify the performance of that system. A fundamental component of a tactile stimulator system is an elastic layer which functions as an anti-aliasing filter. Psychophysical experiments performed measure the ability to statically perceive gratings through an intervening layer of elastic material. Spatial thre...

An approximation technique is considered for computing transmission and reflection coefficients for plane waves propagating through stratified slabs. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is shown that it depends ...

In this paper, we present a fast multipole method (FMM) for the half-space Green’s function in a homogeneous elastic half-space subject to zero normal stress, for which an explicit solution was given by Mindlin (1936). The image structure of this Green’s function is unbounded, so that standard outgoing representations are not easily available. We introduce two such representations here, one inv...
