Cross-Modal Semantic Successive Refinement for Generative Image Communication over Underwater Acoustic Channels
Xu Pei, Bin Wang, Guangxu Zhu +2
Underwater acoustic communication faces challenges such as limited available bandwidth and complex channel environments, which impose demanding requirements on efficient image tran…
Cross-Domain Radiomap Prediction for Multi-Scatterer Environment: A Spherical-Wave-Based Approach
Wenli Li, Bin Wang, Haiyan Fan +3
Radiomap prediction has found extensive applications in network planning and optimization. The radiomap is implicitly determined by electromagnetic (EM) wave propagation. The evolu…
Analytical Method for Metasurface-Based Cloaking Under Arbitrary Oblique Illumination
Yi Zhang, Haiyan Fan, Yujie Zhang +3
The performance of antennas can severely deteriorate in the presence of adjacent electrically-large scatterers. In this work, we use a conducting hollow cylinder to shield the scat…
Ultra-wideband Antireflection Assisted by Continuously Varying Temporal Medium
Yi Zhang, Liang Peng, Zhengjie Huang +2
We demonstrate that reflectionless propagation of electromagnetic waves between two different materials can be achieved by designing an intermediate temporal medium, which can work…
