Terahertz rectification in ring-shaped quantum barriers

Nature Communications, 2018
Many experiments have been performed that study rectification by exciting electrons to tunnel across a single quantum barrier. Here, the authors take a 2-dimensional approach by combining 2D closed-loop tunneling barriers with broken symmetry to enable ...

Anomalous extinction in index-matched terahertz nanogaps

Nanophotonics, 2018
Slot-type nanogaps have been widely utilized in transmission geometry because of their advantages of exclusive light funneling and exact quantification of near-field enhancement at the gap.

Deterministic Aided STAP for Target Detection in Heterogeneous Situations

International Journal of Antennas and Propagation, 2013
Classical space-time adaptive processing (STAP) detectors are strongly limited when facing highly heterogeneous environments. Indeed, in this case, representative target free data are no longer available.
