摘要: The theoretical framework for the computation of electromagnetic fields and electron optical phase-shifts in Fourier space has been recently applied to objects with long-range fringing fields, such as reverse-biased p-n junctions magnetic stripe domains near a specimen edge. In addition new analytical results, this work, we present critical comparison between numerical computations. influence explicit implicit boundary conditions on phase shifts phase-contrast images is also investigated detail.
