Published in 2021 at "Optics Communications"

DOI: 10.1016/j.optcom.2021.127206

Abstract: Abstract Near-field scanning optical microscopy (NSOM) is a promising technique to perform nanoscale fluorescence measurements with a nano-sized near-field-light-source. However, much like a conventional confocal measurement, it requires illuminating the sample with the focus spot… read more here.

Published in 2019 at "Ultramicroscopy"

DOI: 10.1016/j.ultramic.2018.11.003

Abstract: We develop empirical models to predict the contribution of topographic variations in a sample to near-field scanning probe microwave microscopy (NSMM) images. In particular, we focus on |S11| images of a thin Perovskite photovoltaic material… read more here.

Published in 2019 at "IEEE Transactions on Antennas and Propagation"

DOI: 10.1109/tap.2019.2897476

Abstract: A near-field scanning is usually time-consuming to map the electromagnetic field along the surface of a device. In this communication, a dual probe is proposed with a U-shaped loop to sense radio frequency (RF) magnetic… read more here.
