Current research lines

My current research activity focuses on different lines, in cooperation with different researchers and groups.

1. Biomedical signal processing

I am part of a multidisciplinary team that performs research on CAD systems for diagnosis and monitoring of several disorders affecting voice. The considered pathologies are Parkinson’s disease as well as disorders in the field of otorhinolaryngology. My research partners belong to the Bayesian Decision and Inference group of the University of Extremadura (http://bayes.unex.es/).

 

2. Passive microwave circuit design in SIW technology

I am also currently working on the development of passive microwave circuits in substrate integrated waveguide (SIW) technology. The design is based on electromagnetic simulation software developed by researchers from the Telecommunication Research Group (Universidad de Extremadura) in cooperation with researchers from the Computational Electromagnetics Group (Universidad Politécnica de Madrid). More information about these research groups can be found in the following links:

3. Millimeter- and submillimeter-wave monolithic integrated circuit design (MMIC)

The atmospheric windows at 140, 220 and 340 GHz are of great interest for several applications like remote atmospheric sensing, aircraft landing, through-wall imaging, concealed weapon detection, or the next generation of automotive collision-avoidance radar. Submicron device scaling has made transistor-based electronics in the sub-Terahertz range (above 100 GHz) range realizable. This research line currently focuses on the design, fabrication and experimental evaluation of MMICs in this frequency range. This research work is carried out in cooperation with the Fraunhofer Institute for Applied Solid-State Physics in Freiburg, Germany (http://www.iaf.fraunhofer.de/), which is the leading institution in Europe for MMIC design and fabrication above 100 GHz. The MMICs are based on the InAlAs/InGaAs metamorphic HEMT (MHEMT) processes available at the Fraunhofer IAF, in combination with grounded coplanar waveguide technology (GCPW).

4. Hybrid Microwave Integrated Circuits (HMICs) in microstrip and GCPW technology.

This line is carried out in cooperation with the Department of High Frequency Engineering (University of Kassel), led by Prof. Bangert:

There is a bilateral agreement between both universities that allows student exchange in the frame of LLP Erasmus programme. As a result of the cooperation, several master’s and bachelor’s thesis have been realized (see Supervision of Bachelor and Master's thesis in the Teaching Section).
