Propagation loss in SAW devices

Hello!
I use Comsol for SAW device simulations and design some time domain models for SAW delay line. Results (impulse responses) are rather good. Now I want to introduce propagation losses in my models. Standart definition of it is loss per unit length in dB / 1e-6s (dB to microseconds). How can I introduce it in my simulation?

Sergey,
shouldn't the propagation loss be a consequence of the material loss properties?
Cheers
