On Entanglement-Assisted Multistatic Radar Techniques
Entropy, 2022 Entanglement-based quantum sensors have much better sensitivity than corresponding classical sensors in a noisy and lossy regime. In our recent paper, we showed that the entanglement-assisted (EA) joint monostatic–bistatic quantum radar performs much ...

A Modified Hierarchical Vision Transformer for Soil Moisture Retrieval From CYGNSS Data
Water Resources Research, Volume 62, Issue 1, January 2026.Abstract This research introduces a new deep learning (DL) framework, multi‐head self‐attention‐aided vision Transformer (MSA‐ViT), for soil moisture (SM) retrieval using Cyclone Global Navigation Satellite System (CYGNSS) data. We first assess the sensitivity of CYGNSS reflectivity (Γ) $({\Gamma })$ to SM, demonstrating a strong physical linkage ...

Entanglement-Assisted Joint Monostatic-Bistatic Radars
Entropy, 2022 With the help of entanglement, we can build quantum sensors with sensitivity better than that of classical sensors. In this paper we propose an entanglement assisted (EA) joint monostatic-bistatic quantum radar scheme, which significantly outperforms corresponding conventional radars.

The First Results of Ionospheric Skywave Propagation Experiment Over Taiwan
Radio Science, Volume 61, Issue 1, January 2026.Abstract An ionospheric over‐the‐horizon propagation experiment was carried out in Taiwan to investigate characteristics of ionospheric F layer skywave propagation at frequencies 4–12 MHz. Experimental results show that there are prominent diurnal variations in the incident angle, virtual height and plasma frequency at reflection height, which are ...

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.The study presents the design and development of a plasma‐based antenna array system for the UHF band. The system features an omnidirectional plasma antenna as its active radiator, a novel approach that has not been previously explored. Surrounding plasma reflectors form a reconfigurable array around the monopole plasma antenna for beam shaping and ...
