Scientific workshop dedicated to the project

A Scientific workshop entitled “Progresses in development of SAW on GaN structures” has take place in IMT Bucharest, 25.11.2019, in the seminar room. A group of 15 researchers of IMT have participated.

During the Workshop the following papers were presented:

Alexandru Müller - “SAW on GaN devices: rezonators & senzors”

Alina-Cristina Bunea – “Recent developments in microwave filters based on GaN/Si SAW resonators, operating at frequencies above 5 GHz”

Cobianu Cornel - “Technology Platform for SAW Sensing – a Review”

Valentin Buiculecu – “Developments of testing methods for SAW devices and their applications”
