This survey presents a comprehensive review of BM techniques from the perspective of propagation fields. We begin by building the
Based on the Hypergeometric function properties, the analytical expression for the average intensity of Hollow
This misalignment causes the beam to be seen once for every rotation of the neutron star, which leads to
Laser beams are light beams propagating dominantly in one direction, i.e., with low beam divergence. This is possible due to the
Near infrared is the region closest in wavelength to the radiation detectable by the human eye. Mid and far infrared are progressively
This paper exploits the potential of JPTA to simultaneously serve multiple users in both near- and far-field regions with a single radio
