“…where ξ is the ratio of speed of Rayleigh waves to transverse waves, c t is the transverse speed of sound and Q c is the maximum surface wave vector. We take for pSi (P = 92.9%) ξ ≈ 0.88 and c t /c l ≈ 0.694, which follows from cSi data [6]. (Ref.…”

“…This material has been widely used for the fabrication of optical devices, including optical filters where the refractive index can be varied through a variation of the porosity [66]. There are also studies of the variation of acoustical properties, including the acoustical impedance, due to the variation of the porosity [70] [71]. Recently, acoustic multilayer mirrors have been made using porous silicon [72].…”

Using the transfer matrix method we calculate the frequency dependence of the transmission of longitudinal elastic waves for a layered structure where the specific acoustic impedance of the layers with odd numbering follows a Gaussian distribution, while the inserted even layers have the same impedance as the propagation medium. The structure presents intervals of low-pass, bandstop, and band-pass. The characteristics of the bands depend on the number of layers, on the contrast between the maximum and minimum impedances of the structure, and on the ratio of the width of the inserted layers to the width of the layers with a Gaussian distribution of impedances.
