WebKnife Edge Model. The path loss due to diffraction in the knife edge model is controlled by the Fresnel Diffraction Parameter which measures how deep the receiver is within the shadowed region. A negative value for the parameter shows that the obstruction is below the line of sight and if the value is below -1 there is hardly any loss. touristeninformation kitzingenWebKnife Edge Diffraction 6C20.15 KNIFE EDGE DIFFRACTION Version 1 A laser beam forms a diffraction pattern at the edge of a razor blade.
