WebOct 1, 1994 · A new technique of free-space simulation has been developed for solving unbounded electromagnetic problems with the finite-difference time-domain method. Referred to as PML, the new technique is based on the use of an absorbing layer especially designed to absorb without reflection the electromagnetic waves. Specifically, for a PML designed to absorb waves propagating in the x direction, the following transformation is included in the wave equation. Wherever an x derivative appears in the wave equation, it is replaced by: where is the angular frequency and is some function of x. Wherever is positive, propagating waves are attenuated because:
WebFinite Difference Beam Propagation Method (FD-BPM) with Perfectly Matched Layers. We consider a planar waveguide where x and z are the transverse and propagation directions, respectively, and there is no variation in the y direction ( ∂ ⁄ ∂ y ≡ 0 ) . Furthermore we consider that the planar optical waveguide with width W is surrounded by ...

WebPML with grazing incident angles. To resolve these issues, the Complex-Frequency-Shifted PML (CFS-PML) method was proposed in [10]. This is a class of PMLs that uses more general complex transformation functions than those in [5]. We will denote PML formulations that uses the original WebIn this paper, we present a nonsplitting perfectly matched layer (NPML) method for the finite‐difference simulation of elastic wave propagation. Compared to the conventional split‐field approach, the new formulation solves the same set of equations for the boundary and interior regions. The nonsplitting formulation simplifies the perfectly matched layer …
Webis called the split-field PML, because he artificially split the wave solutions into th e sum of two new artificial field components. Nowadays, a more co mmon formulation is the uniaxial PML or UPML, which expresses the PML region as the ordinary wave equation with a combination of artificial anisotropic absorbing materials [3]. Both
