Published in 2022 at "IEEE Access"

DOI: 10.1109/access.2022.3223868

Abstract: Ray tracing is replacing the less accurate statistical and empirical approaches of radio channel modeling. Although being high-frequency asymptotic method, ray tracing has been shown to be mathematically equivalent to purely analytical modal methods in… read more here.
