WebJun 1, 1980 · The complex effective dielectric constant of an inhomogeneous medium, as calculated with the Effective Medium Theory (E.M.T.), is the solution of a quadratic equation and is therefore a multiple-valued function. In most cases, physical criteria alone are not sufficient to select the solution which has a physical meaning. WebThe rate of adoption will depend upon the sources of communication, even more so than the technical information contained in the messages (Lundblad, 2003). Time is the third element of the theory. According to Rogers (2003), who developed the Theory of the Diffusion of Innovation, three considerations are related to the time element.
