oa Intrinsic Attenuation in a Periodically Layered Medium

In this paper, I introduce the intrinsic attenuation for periodically layered structure to investigate how the intrinsic attenuation interferes with the scattering due to layering. The presence of intrinsic attenuation results in the stretch of reflection and transmission responses in frequency domain. I show that the anomalies in energy loss follow the stop-bands in frequency scale which are wider for higher acoustic contrast between the layers.
