Measurement, simulation, and characterization of train-to-infrastructure inside-station channel at the terahertz band
In this paper, we measure, simulate, and characterize the train-to-infrastructure (T2I) inside-
station channel at the terahertz (THz) band for the first time. To begin with, a series of …

Towards realistic high-speed train channels at 5G millimeter-wave band—Part II: Case study for paradigm implementation
In this paper, we present two case studies for generating realistic high-speed train (HST)
channels at fifth-generation (5G) millimeter-wave (mmWave) band. The first one is the tunnel …

Dynamically reversible and strong circular dichroism based on Babinet-invertible chiral metasurfaces
We propose a Babinet-invertible chiral metasurface for achieving dynamically reversible and
strong circular dichroism (CD). The proposed metasurface is composed of a VO 2–metal …
