The propagation of soft x‐rays generated by a small‐diameter incoherent source through a tapered, plane capillary‐type waveguide was studied using the Fresnel–Kirchhoff theory and method of images. The diffraction and interference are manifested by the appearance of the diffraction fringes in both the near‐ and far‐field zones of the waveguide output. The experimental data confirm such behaviour of the x‐radiation. Copyright © 2000 John Wiley & Sons, Ltd.
