  • Title: Complex coordinate implementation in the curvilinear coordinate method: application to plane-wave diffraction by nonperiodic rough surfaces.
    Author: Edee K, Granet G, Plumey JP.
    Journal: J Opt Soc Am A Opt Image Sci Vis; 2007 Apr; 24(4):1097-102. PubMed ID: 17361297.
    Abstract:
    We investigate the electromagnetic modeling of plane-wave diffraction by nonperiodic surfaces by using the curvilinear coordinate method (CCM). This method is often used with a Fourier basis expansion, which results in the periodization of both the geometry and the electromagnetic field. We write the CCM in a complex coordinate system in order to introduce the perfectly matched layer concept in a simple and efficient way. The results, presented for a perfectly conducting surface, show the efficiency of the model.
