Novel Beam Scan Method of Fabry–Perot Cavity (FPC) Antennas
Applied Sciences, 2021 A new beam scanning method of a Fabry–Perot cavity (FPC) antenna is proposed. To obtain high gain in a target direction with a reduced sidelobe level (SLL), we devised a tapered partially reflective surface (PRS) as a superstrate.

Golden beam data for proton pencil-beam scanning [PDF]
Physics in Medicine and Biology, 2012 Proton, as well as other ion, beams applied by electro-magnetic deflection in pencil-beam scanning (PBS) are minimally perturbed and thus can be quantified a priori by their fundamental interactions in a medium. This a priori quantification permits an optimal reduction of characterizing measurements on a particular PBS delivery system.
