Mixing formulas in time domain
Author
Summary, in English
This paper discusses the dispersive properties of dielectric materials both in
the time and the frequency domains. Special emphasis is on the treatment
of heterogeneous materials, in particular two-phase mixtures. A time domain
Maxwell Garnett rule is derived which differs from the corresponding
frequency domain formula in the respect that it is expressed in terms of convolutions
and inverse operators of the susceptibility kernels of the materials.
Much of the analysis deals with the question how the temporal dispersion of
the dielectric response of various physical materials is affected by the mixing
process. Debye, Lorentz, Drude, and modified Debye susceptibility models
are treated in detail.
