Description:

Resonators act as a frequency reference or to filter specific frequencies. Used in such products as cell phones or computers, resonators will allow the user to take advantage of high bandwidths to process and send greater amounts of data. When used in medical devises such as MRIs they can detect microorganisms and biological molecules. The dilemma that Researcher face when building these micro resonators is that the smaller a resonator gets the less reliable it becomes. Based on his research at Cornell University, the author employs current modeling and fabrication technologies to bring a solution to this seemingly insurmountable problem one step closer. Microresonators are fundamental…

Nicolae Lobontiu, Ph.D is associate professor of mechanical engineering at the University of Alaska Anchorage. His teaching background has run the gamut of mechanical engineering, including: system dynamics, controls, instrumentation and measurement, mechanics of materials, dynamics, vibrations, finite element analysis, boundary element analysis, and thermal system design. Professor Lobontiu's research interests for the last decade have focused on compliant mechanisms (mechanical devices which move by elastic deformation of their flexible joints) and micro/nano electromechanical systems. He has authored four books and 20 peer-reviewed journal papers on the aforementioned research topics.
