Abstract. The analysis of point-to-point correlation functions of casual
quasiperiodic structure is given and analytical decisions for tensors of
effective properties of quasiperiodic piezoelectro-magnetic composites in the
form of a linear combination of the known relevant decisions for tensors of
effective properties of composites from ideally periodic and polydisperse
structures are received. New decisions included "frequency
coefficient", this is coefficient of correlation of quasiperiodic and
periodic structures. The numerical analysis of influence of aperiodicity and inversion of properties of phases on values of
longitudinal coefficient of electromagnetic communication of a composite with
quasiperiodic unidirectional fibrous structure from piezoelectric (PVF) and piezomagnetic
(ferrite) of phases is submitted. New effects are revealed and comparison of
results of calculation with known decisions of other authors is carried out.
Keywords: piezocomposite, electro-magnetic elasticity, effective properties, quasiperiodic
