Microwave dielectric properties of fiber-filled composites attract considerable attention due to their numerous applications. We present results of experimental investigation of the dielectric properties that reveals a great variety of types of dielectric dispersion in these materials. The...

Effective medium theories (EMTs) along with percolation theory allow the characterization of the electromagnetic properties of binary composite mixtures at a frequency when the scale of a particle size allows the quasi-static limit approximation. These theories formulate an effective...

We study the influence of the transition between ferromagnetism and superparamagnetism on optical properties. The samples are thin nanocermet films where ferromagnetic monodomain inclusions of Ni are embedded in an AlN matrix. The optical measurements, performed on a Fourier transform...

Models accounting for the optical properties of non-scattering and scattering media with complex morphologies are reviewed. The emphasis is put on non-scattering media near the percolation threshold and scattering media with high scatterer concentration. The connection with experiment on real...

Angular selective coatings are of interest for innovative fenestration. A theoretical framework, based on the Maxwell Garnett and Bruggeman effective medium theories, is put forward. These theories are applied to obliquely sputter deposited films based on Cr, Al, or Ti. A detailed representation...
