   Hi, I'm looking into testing Pharmaceutical tablets with 2 different sets of transducers. They're set up so one of them Transmits/Receives and the other one Transmits. They are shear wave and longitudinal wave.

   From what I understand, K-wave can only handle the analysis of longitudinal waves (is this right?). I'm interested in testing for thickness, hardness, porosity, and weight. I have a prototype that can apply a variable pressure. My goal for it is to be able to see the change in elastic relationships based on the pressure applied to the porous pill.

   At this point, I'm just starting off so I figured I'd post here to get any insights on what my next steps should be. I.e. Would K-wave be useful to analyze the longitudinal responses based on the pressure applied to the tablet with air-coupled transducers?

   Also, are there any other packages that can handle the shear wave analysis?

   The longitudinal transducers are 3.5Mhz and the shear wave are 1Mhz.

   As you say, the current version of k-Wave only models longitudinal waves (although an elastic wave version will be released in due course). As the shear waves and longitudinal waves are coupled (energy is converted from one mode to the other at material interfaces), just considering the longitudinal waves won't necessarily give you useful results. You could try looking at some of the other packages in this list.
