UWB on-body radio channel modeling using ray theory and subband FDTD method (2006, background): “The conventional and empirical channel models available for many narrowband and wideband systems are insufficient to describe UWB channel behavior due to the UWB nature of the transmitted signals.”
A review of antennas and propagation for MIMO wireless communications (2004, background): “Recent studies have further combined ray-tracing with full-wave electromagnetic solvers to model objects with features that are comparable to the illumination wavelength [79], [80].”
Terahertz Wireless Channels: A Holistic Survey on Measurement, Modeling, and Analysis (2021, methodology): “Reference [185] studies single interactions between ray-tracing and FDTD where the location of the Rx is restricted in the FDTD region, for example the corner of the room.”
Terahertz Band Communication: An Old Problem Revisited and Research Directions for the Next Decade (2021, methodology): “For instance, a combination of RT and FDTD methods can realize accurate modeling in a time-efﬁcient manner [155].”
