Micius quantum experiments in space (2022, methodology): “For a downlink, it is recommended to set the FWHM beam waist to be half of the transmitting telescope diameter (Stutzman and Thiele, 2012).”
A Tutorial on Near-Field XL-MIMO Communications Toward 6G (2023, unknown): “For free-space LoS propagation between s and p m , both α m and ϕ m depend on the link distance r m , given by  where U m accounts for the characteristic of the individual array element, such as directional gain pattern [30], [31].”
A Reconfigurable Active Huygens' Metalens (2017, background): “By assuming in-phase radiation from all virtual sources, the superposition of the radiated fields is mapped onto the recording plane where the metalens is located (z = 0), and the interference electric field is retrieved as[61]”
