I do not think so - what is the operating frequency/driving freq., and thickness of the substrate (also material)?
Finally, why do expect guided/surface waves on the substrate (have you measured them or)?
ALso is this part of a research project, and are you a research student (you only provide a gmail, so I can not see if you are a research student)?
In any case we do not have any material on this.

Thank you
