Sub‐Nanometer Ferroelectric Tunnel Junctions With Record‐High on‐Current Density Through Synergistic Microwave Annealing and High‐Field Activation

Small, Volume 22, Issue 36, 26 June 2026.
ABSTRACT High‐density memory systems require a high on‐state current density (Jon) to ensure fast read speeds and large sensing margins in cross‐point array applications. However, achieving high Jon in atomically thin ferroelectric tunnel junctions (FTJs) remains an unmet challenge, hindered by parasitic interfacial layer (IL), depolarization fields ...

Passive microwave camera

Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002
A novel microwave imaging technique that is completely passive and has the ability to image objects and scenes that are obscured by smoke, fog, clouds, building materials, and opaque barriers has been developed. The system employs a electrooptic approach to reduce system complexity and cost by orders of magnitude over competing real-time high ...

Numerical modelling of passive microwave devices

Computer-Aided Design, 1974
Passive linear bilateral microwave devices principally include guided wave transmission structures, their junctions, and interconnections, as well as such complex devices as resonant cavities and planar networks. The computational methods for analyzing the behavior of this class of structures and for characterizing them for purposes of network design ...

On passive intermodulation at microwave frequencies

Asia-Pacific Conference on Environmental Electromagnetics, 2003. CEEM 2003. Proceedings., 2003
The appearance of PIM products bring a lot of harm into modern satellite communication systems. In this paper, the fundamental concept, mechanism and prediction of PIM are studied. And one mathematical model is given, which is able to predict high order PIM level by using low order PIM level.
