Research topics:

Measurement techniques and modeling of the nonlinear behavior of passive devices

Analysis, modelling and measurements of passive intermodulation due to intrinsic properties of the materials: superconductor, ferroelectric, piezoelectric, etc., or extrinsic effects: thermal effects, impurities, metal contacts, etc. We also asses the effects of the nonlinearities on the performance of a final prototype or a market product.

Design of microwave and RF filters for communications (electro-acoustic, multiband, reconfigurable, etc.)

Development of advanced microwave and acoustic devices and systems based on an accurate process of characterization, modeling and design.
