Abstract
Using exact dispersion relations for electromagnetic wave propagation in layered,
periodic media, consisting of two phases, we derive explicit asymptotic
solutions for small wavenumbers. These solutions are compared to the numerical
solutions of the exact dispersion relations, and applications to homogenization
problems are discussed. The results can be used as test cases
for homogenization techniques intended for finite scale homogenization, that
is, where the wavelength is not assumed infinitely large compared to the microscale.
