WebVarious codes propose their own definitions of the effective width based on the beam span and the slab width Revised: 21 May 2024 parameters. However, the evaluation of the effective width may be influenced by other parameters. The aim of this work is Accepted: 24 May 2024 to determine the most important factors affecting effective width for ... The beam diameter or beam width of an electromagnetic beam is the diameter along any specified line that is perpendicular to the beam axis and intersects it. Since beams typically do not have sharp edges, the diameter can be defined in many different ways. Five definitions of the beam width are in common use: D4σ, 10/90 or 20/80 knife-edge, 1/e , FWHM, and D86. The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it ca… tribal boundaries nz
