Acoustics of fractal porous material and fractional calculus
(MDPI, 2021)In this paper, we present a fractal (self-similar) model of acoustic propagation in a porous material with a rigid structure. The fractal medium is modeled as a continuous medium of non-integer spatial dimension. The basic ...
