Abstract :
This paper presents the Perfectly Matched Layers (PMLs) in the framework of transformation optics as a complex-valued change of coordinates. PMLs provide the suitable operator extensions required for the quasi-mode analysis of open problems. Leaky modes in open dielectric waveguides and spectral analysis of diffraction gratings are considered here.
