| Abstract |
In this thesis the properties of light in complex dielectrics are described, with the two general topics of "modification of spontaneous emission" and "Anderson localization of light". The first part focuses on the spontaneous emission rate of an excited atom in a dielectric host with variable refractive index, with the aim to identify which local-field correction applies to spontaneous emission. The second part deals with the propagation of visible light in a medium with extremely strong scattering, close to the Anderson localization transition.
