openTMM 0.1.0

openTMM is an object-oriented electrodynamic S-matrix (transfer matrix) code with modern applications.

Electromagnetic wave propagation through planar stratified media (multilayer stack); the three-dimensional space is divided into layers. The interfaces separating the layers are assumed to be perfectly planar and the layers are assumed to be isotropic and homogeneous, with a complex permittivity and permeability. Moreover, the layers may be composed of a left-handed material (negative refractive material) and/or a right-handed material. The implementation is suitable for the study of modern applications, e.g., Anderson localization of light and sub-wavelength imaging.

For more details see our preprint, openTMMpreprint.pdf, which is distributed with the source code. The preprint was also published in the Journal of Computational Physics (2012) 231:14, 4823-4835. http://dx.doi.org/10.1016/j.jcp.2012.03.018

MAJOR CHANGES IN VERSION 0.1.0:

• Changed standard transfer matrix alg. to S-matrix alg. The solution should now be numerically stable in presence of large absorption.

• Rewrote openTMMpreprint.pdf. It now includes a discussion of different transfer matrix algorithms and performance comparison of python to Fortran 90/95 as well as numerical stability tests.
