In addition, a software package for computing the actual reflection from a FDTD-PML is provided. Finally, a review of the literature on the application of the PML ABC to other numerical techniques of electromagnetics and to other partial differential equations of physics is provided. Commercial software such as ANSYS/CFX, FLUENT, and COMSOL Multiphysics or written codes such as lattice Boltzmann technology are used for numerical simulation of many food processes (Sun, 2002 Sun and Hu, 2002) including fluid mixing, whereas finite volume method and finite element method (FEM) have been used to solve the velocity field. The optimization of the PML ABC is addressed in two typical applications of the FDTD method: first, wave-structure interaction problems, and secondly, waveguide problems. Propagation and reflection of waves in the discretized FDTD space are derived and discussed, with a special emphasis on the problem of evanescent waves. The implementation of the PML ABC in the FDTD method is presented in detail. I had calculated the transmission spectra vs wavelength.
In FDTD, we use dipole source as in meaning of QD.
Why i m preferring dipole source means, I m dealing with Quantum dots (QD). Actually I did FDTD simulation with this structure. The frequency domain and the time domain equations are derived for the different forms of PML media, namely the split PML, the CPML, the NPML, and the uniaxial PML, in the cases of PMLs matched to isotropic, anisotropic, and dispersive media. Coming to this topic, I will explain my focus. It can be deleted using the delete key or the backspace key. I think the best starting point would be the Y splitter example from the Application Gallery: This is an embed external element.
This lecture presents the perfectly matched layer (PML) absorbing boundary condition (ABC) used to simulate free space when solving the Maxwell equations with such finite methods as the finite difference time domain (FDTD) method or the finite element method. While the EME solver would probably be more efficient for a basic MMI structure, as you mentioned, an FDTD simulation of an MMI shouldn't be too complicated.
