Scanning probe microscopy at microwave and infrared wavelengths

Veranstalter:  Prof. Dr. Andrea Di Donato, Università Politecnica delle Marche/ Ancona, Italien
Ort:  A1-3-330

Abstract:
The talk will review the features of some novel techniques in the field of Scanning Microscopy, in which is
constantly growing the need for innovative and accurate imaging/spectroscopic methods. In particular, Scan-
ning Microwave Microscopy (SMM) and Near Infrared Scanning Microscopy, based on extrinsic Fabry-Perot
optical cavity, will be discussed. The former offers the advantage to achieve nanometric resolution, both on
inorganic and organic samples, whereas the latter combines the high sensitivity of the extrinsic micro-cavity
with the features of a low coherence source to achieve quantitative phase imaging. The SMM system is inte-
grated in a Scanning Tunneling Microscope, while Near Infrared Microscope is totally realized in optical
fiber in order to have a compact and lens-free system.
Brief biography:
Dr. Andrea Di Donato is Assistant Professor at Polytechnic University of Marche. He graduated in Electronic
Engineering from University of Ancona in 2000, and completed the Ph.D. in Electromagnetics (2004) at
Polytechnic University of Marche. From 2003 to 2007 he was involved in different research fellowships in
Electromagnetics regarding Microwave and Optical wave interaction inside anisotropic waveguides. In 2007
he was working with Somacis Spa company on the analysis and characterization of Polymeric Optical Printed
Circuit Boards. Since 2010 he was appointed as Assistant Professor at Polytechnic University of Marche and
since 2016 as Research Scholar at Harvard School of Engineering and Applied Sciences. In 2014 he founded
the start-up Micro&Nano Lab, a company whose main activity was related to development of novel tech-
niques and imaging systems in scanning microscopy. His latest research interest focuses on development of
novel techniques applied to scanning microscopy, in particular he was recently involved in Scanning Micro-
wave Microscopy and Near Infrared Scanning Microscopy for high sensitive quantitative phase-imaging.
