DOI: 10.1002/jemt.23113

Abstract: Inserting an electrically tunable lens (ETL), such as liquid lens or tunable acoustic gradient lens, into a microscope can enable fast axial scanning, autofocusing, and extended depth of field. However, placing the ETL at different… read more here.

DOI: 10.1109/tap.2019.2957079

Abstract: This article presents a technique designed to extend the scanning range of a probe-fed patch array whose performances are limited by scan blindness, due to a strong surface wave coupling. The current framework relates to… read more here.
