N2 - Waves of an arbitrary frequency in a porous elastic medium are investigated via the Kramers-Kronig relations method. It is shown that some of the widely accepted theories of wave propagation in random composites may violate the causality and/or linearity of the effective medium. Experimentally observed dynamic effects in random media, such as stop bands and complicated behavior of the dispersion curve, are shown to follow from the K-K relations.
