Abstract:

Several approximations to the attenuation coefficient caused by double knife-edge diffraction are given in terms of the single knife-edge attenuation coefficient. These approximations are evaluated for several typical double knife-edge paths and compared with the theoretical value in order to de­termine the best approximation in the different regions of interest.
