In this paper we present an analysis of the optical and microwave properties of metal-ammonia solutions in the concentration range 2-9 MPM. The analysis rests on the physical picture of a continuous metal-nonmetal transition, intermediated by microscopic inhomogeneities originating from bimodal concentration fluctuations. Effective-medium theory for the complex dielectric constant gives a good account of the optical properties of Li-NH 3 in the energy range 0.6-1.4 eV. On the other hand, effective-medium theory is inadequate for the microwave properties, and results of numerical simulation are presented.
