IMT-Bucharest (National Institute for Research and Development in Microtechnologies), coordinated by the Romanian Ministry of Education and Research, is the first institute with this profile in Eastern Europe and the main actor in microtechnologies in Romania. There are more than 100 people involved in research activities. Mission: research and development in micro- and nanotechnologies, technology transfer, education and training, dissemination; strategic role: pole of multidisciplinary research, integrating research, education and technology transfer, emerging as a regional centre. Research laboratories: Nanotechnologies, Microsystems for Bio-medical applications, Micro- and Nano-photonics, Micromachined microwave and millimeter wave circuits, Computer-aided simulation and modelling, Microphysical characterization, reliability. Participation in FP7 relevant to this project are MIMOMEMS (lead by IMT) , NANOTEC and SMARTPOWER; ENIAC projects: MERCURE , NANOCOM, NANORF. The relevant research of Laboratory of Micromachined microwave and millimeter wave circuits: IMT-Bucharest has an unique expertise in RF MEMS and carbon-based electronics. IMT is promoting the field of Membrane supported millimeter wave circuits since 1996 and carbon-based electronics since 2007. The “Laboratory of micromachined microwave circuits” is also a national Center of Excellence in RF MEMS. The scientists from this group have published an important number of high-quality papers in the area of carbon nanotubes, graphene and 2D materials-based devices.We have researched and fabricated with FORTH Heraklion or alone a long series of RF carbon nanotube devices ( waveguides, amplifiers, resonators, memristors, biosensors) Also, we have fabricated for the first time with FORTH Heraklion microwave graphene devices (waveguides, FETs, multipliers, and demodulators) demonstrating how much the microwave devices are enhance using graphene. The first results for microwave devices using other 2D materials were published starting 2014.
