Band bending is an effective way to kill viruses because the technique allows electrons, which were freed by the UV, to travel forward and create hydroxyl radicals by reacting with water.
Here a scheme to implement broad-band constant beamwidth digital beam-former has been presented. The results of computer simulation show the scheme is effective.
