Leaky and bound modes of surface plasmon waveguides
TL;DR: In this paper, a full-vectorial, magnetic field finite-difference method with complex coordinate stretching perfectly matched layer boundary conditions was used to solve for both the leaky and bound modes of metallic slab and stripe waveguides.

The failure of perfectly matched layers, and towards their redemption by adiabatic absorbers.
TL;DR: The fundamental connection between reflections and the smoothness of the absorption profile via coupled-mode theory is demonstrated, and it is shown how to obtain higher-order and even exponential vanishing of the reflection with absorber thickness.

Validation and extension to three dimensions of the Berenger PML absorbing boundary condition for FD-TD meshes
TL;DR: In this article, a novel absorbing boundary condition (ABC) for FD-TD meshes in two dimensions, called the "perfectly matched layer (PML) for the absorption of electromagnetic waves", was proposed.
Semivectorial polarised finite difference method for optical waveguides with arbitrary index profiles
TL;DR: In this paper, a simple accurate method, which automatically takes full account of the discontinuities in the normal electric field components across any arbitrary distribution of internal dielectric interfaces, is presented for the determination of polarised solutions of the Helmholtz wave equation.

Perfectly matched absorbing boundary conditions based on anisotropic lossy mapping of space
TL;DR: An absorbing boundary condition (ABC), based on the PML BBC of Berenger (1994), used in the frequency domain to terminate the computational grid in electromagnetic scattering simulations is presented, using an impedance-matched lossy layer with directionally-dependent electric and magnetic conductivity.

Review of numerical and approximate methods for the modal analysis of general optical dielectric waveguides
TL;DR: Numerical and approximate methods for the modal analysis of general optical dielectric waveguides with emphasis on recent developments are reviewed, ranging from the specialized ones for analysing restricted classes of waveguide to the most general ones for analyseing inhomogeneous, arbitrarily-shaped, anisotropic waveguiding.
