The interaction of mm and THz waves with materials is described by the dielectric permittivity and magnetic permeability function. The research work in this area concerns:

• Characterization of material properties using quasi-optical vector based measurement techniques (S-parameters)

• Development of powerful and robust hierarchical algorithms (combinations of direct and indirect techniques) to extract material properties of single and multi-layer structures

• Evaluation of dielectric mixing models of compounds and mixtures

• Process control of industrial processes

The materials of our interest include: technology materials for realizing integrated and packaged electronic circuits and systems: semiconductors (Si, GaAs), dielectrics, insulators (BCB), ceramics, polymers, liquids, powders, granular materials, mixtures… The target industries can be very diverse: electronic, chemical, food, pharmacy, biotech, agriculture, construction,…
