Next-generation smart systems [description of the field]

L4- Micromachined Structures, Microwave Circuits and Devices Laboratory

1. Mission

Scientific research and technological development of RF MEMS (microwave micromachined devices and circuits), contributions to the developing strategy of the domain. The new RF MEMS concept represents a solution to manufacture high performance microwave and millimeter wave devices and circuits using MEMS technologies. The laboratory is one of the promoters of the RF – MEMS domain in Europe, coordinator of a European successful project in this domain and participant in FP6 network of excellence.

2. Competence related to the field

We provide competence in the field Micro/Nanosystems  - New generation smart systems in the following topics:

    • Development of a new generation of circuits devoted to the millimeter wave communications based on the semiconductor (Si, GaAs, GaN) micromachining and nanoprocessing materials
    • Design, modeling and simulations of microwave and millimeter wave components and circuits
    • Silicon, GaAs and GaN micromachining
    • Manufacturing of micromachined Yagi-Uda antennae; monolithically and hybrid integrated receiver modules; receiver modules integrated with Yagi-Uda antenna.
    •  Design, modelling and manufacturing reconfigurable millimeter wave circuits for wireless communication systems
    •  Electromagnetical modelling of RF switches
    •  Studies on magnetostatic wave resonators in microstrip and CPW configurations
    •  Design, modelling and manufacturing F-BARS on compound semiconductors
    •  MEMS and NEMS  technologies development
    •  Smart micro/nanosystems enabling wireless access for communicatins systems

3. Key people

Dr. Alexandru Müller (alexm@imt.ro) graduated the University of Bucharest, Faculty of Physics in 1972; PhD degree in Semiconductor Physics in 1990.. As a senior scientist at IMT-Bucharest, his main research areas are micromechanics on silicon and GaAs, design and manufacturing of microwave circuits supported on thin dielectric membranes, membrane supported millimetre wave filters, antennae and receiver modules. Dr. Müller coordinated the FP4 Project “MEMSWAVE – Micromachined Circuits for Microwave and Millimetre Wave Applications”, nominated between the first 10 European research projects at the 2002 call for the DESCARTES prize of the EC. He also has coordinates bilateral cooperation projects with: LAAS-CNRS Toulouse, FORTH-IESL-MRG Heraklion, ITC-IRST Trento and the Romanian team in “AMICOM” FP6 NoE in RF-MEMS. (2004-2007). He is the author of more than 75 papers published in journals and Conference Proceedings and also co-author in 6 books. In 2002, he was awarded with the “Tudor Tanasescu” Prize of the Romanian Academy.

He is a principal researcher at IMT-Bucharest. He was a visiting professor with Univ. Duisburg, Mannheim, Frankfurt and Darmstadt, Germany, Tor Vergata University, Rome, Italy, Univ. Saint-Etienne, France. He is the author 127 papers (in journals and proceedings of conferences) in the area of microwave, millimeter-wave, terahertz, RF-MEMS, Optical-MEMS (MOEMS) and nanoelectronics. He is the co-author of the following books: Advanced Optoelectronic Devices (Springer, 1999), Optical Characterization of Solids (Springer, 2002), Quantum – Classical Analogies (Springer, 2003) and Nanoelectronics (Artech House, 2005). His current research interests are nanodevices, RF-MEMS and terahertz electronics. He is the recipient of the 1991 Alexander von Humboldt Fellowship, and the 1999 Romanian Academy Prize “Gh. Cartianu”. In 2003 he had a invited “Dirctor de recherché” position at LAAS-CNRS Toulouse.

Dr. Dan Neculoiu (neculoiu@imt.ro) graduated the Polytechnical Institute of Bucharest, Faculty of Electronics in 1985; PhD degree in 1997.. As a senior scientist at IMT-Bucharest, his main research areas are the electromagnetic simulations for the design and modelling of microwave circuits, membrane supported millimetre wave filters, antennae and receiver modules. He participated in the FP4 Project “MEMSWAVE” and in FP6 NoE in RF-MEMS “AMICOM”. Dr Neculoiu has coordinated a Brancusi project (2003) and has participated in two IMPACT projects (2001-2002) financed by EC, with LAAS-CNRS. He is the author of more than 100 papers published in journals and Conference Proceedings in the area of RF-MEMS. Dr Dan Neculoiu is also full professor at the “Politehnica” University Bucharest.
