The EMT estimates are shown to be in good agreement with available experimental results. Porous piezoelectric ceramics are also discussed. The EMT predicts a similar critical behavior for heterogeneous piezoelectric materials to recent experiments.","authors":[],"categoryName":"|","doi":"","fpage":"1155","id":"e7f59558-e05d-411c-962c-b1cfd1cce558","issue":"2","journal":{"abbrevTitle":"JOAP","id":"7dcf8a89-0513-40ee-be2d-759941dcef7e","issnPpub":"0021-8979","publisherId":"JOAP","title":"Journal of Applied Physics"},"keywords":[{"id":"941e4dc1-7057-468d-89f9-6b7b1fc4028f","keyword":"electromechanical properties;ceramics","originalKeyword":"electromechanical properties;ceramics"}],"language":"en","publisherId":"0021-8979_1994_2_1","title":"<span style=\"color:red\">EFFECTIVE-MEDIUM</span> <span style=\"color:red\">THEORY</span> OF PIEZOELECTRIC COMPOSITES","volume":"76","year":"1994"},{"abstractinfo":"As an analytical method, the <span style=\"color:red\">effective</span>-field <span style=\"color:red\">theory</span> (EFT) is used to study the dynamical response of the kinetic Ising model in the presence of a sinusoidal oscillating field.
