Forecasting Ionospheric Irregularities on GNSS Lines of Sight Using Dynamic Graphs with Ephemeris Conditioning
Mert Can Turkmen, Eng Leong Tan, Yee Hui Lee
Most data-driven ionospheric models operate on gridded products, which do not preserve the time-varying sampling structure of satellite-based sensing. We instead model the ionosphe…

Focusing Metasurfaces of (Un)equal Power Allocations for Wireless Power Transfer
Andi Ding, Yee Hui Lee, Eng Leong Tan +5
Focusing metasurfaces (MTSs) tailored for different power allocations in wireless power transfer (WPT) system are proposed in this letter. The designed metasurface unit cells ensur…
