To convert from SI to MEEP: divide by the MEEP base unit (expressed in SI units).Īnd on a another note: for complex \(\epsilon\) with lossy materials, where the permittivity must be expressed as a complex number (or even a Fourier series), MEEP does support it as well, but then the conversions might get slightly more intricate.įor the purposes of this post, let’s assume that the most ugly materials we deal with can be represented by just a complex \(\epsilon, \mu\) (see this the docs for more details).

To convert from MEEP to SI: multiply by the MEEP base unit (expressed in SI units).

In short, to get MEEP working 100%, at the start of the notebook run: If you want to get started using google colab notebooks (which are run on linux backends), then you need to do some special path stuffs to get it to work nicely. In particular, we focus on aspects of implementing a full-featured FDTD package that go beyond standard.

This paper describes MEEP, a popular free implementation of the finite-difference time-domain (FDTD) method for simulating electromagnetism.

You can get around this hurdle on windows if you use the Windows Subsystem for Linux, but it is a bit buggy. MEEP: A flexible free-software package for electromagnetic simulations by the FDTD method. Bad news: MEEP does not support windows as of. So here I present a quick intro for those who have only taken one or two undergraduate modules in electromagnetics to get started with using MEEP. However, the documentation and introductions appear to be more geared toward people who know a lot more about it than me, and seems to be more focused on photonics than simulation of basic things like electric/magnetic field intensity. It seems to work pretty well, and has quite a reasonable python interface, and allows for a wide range of kinds of electromagnetic simulations.

TL DR: While looking for a nice open source piece of electromagnetics simulation software, particularly ones which could be scripted using python, I found MEEP. This paper contains detailed information on the cavity structure as well as. This is accomplished by reproducing the results in the paper by Y. I post about deep learning, electronics, and other things I find interesting.Ģ2 December 2019 Getting started with MEEP - simple electric field simulations in pythonĪ quick intro to simulating the electric field for simple current distributions in python using MEEP. The goal of this example is to demonstrate how FDTD may be used to analyze photonic crystal nanocavities such as the one shown below. I am an E&E masters student at Stellenbosch University.
