Rigorous coupled wave analysis (RCWA) based on the scattering matrix (SM) algorithm is one of the most powerful tools for the electromagnetic simulation of patterned multilayer structures.
PPML - RCWA is a project which implements the SM-RCWA, based on the formalisms of [a-d].
Two groups of functions are available: one is for 1-d patterns, the other for 2-d patterns.
Not all the features available for 1-d patterns are available for 2-d ones, and vice-versa.
For 1-d patterns, currently available are functions for the calculation of
i) intensity reflectance, transmittance, and layer-by-layer absorbance
ii) the full 2x2 scattering matrix
iii) the E and S fields inside the structure
1-d patterns are only supported for TM-polarization, i.e., p-polarized incident waves belonging to the plane orthogonal to the pattern (see the Manual for details).
This specificity, together with the proper factorization rules [c,d], make the code extremely performing, and fully suitable for the simulation of metal components (plasmonic gratings).
Anisotropic materials can be treated.
For 2-d patterns, currently available are functions for the calculation of
i) polarization-resolved reflection coefficients
Allowed unit cell geometries are rectangular and L-shaped inclusions (see the Manual for details). The proper factorization rules are implemented [c,d], thus allowing for a fast convergence even in presence of metallic inclusions.
The present code is distributed for free, but we kindly ask you to cite its source and, if applies, the publications below.
Several publications are based on PPML 1.1 (see below). For some of them, you can find the corresponding tutorial in the software package.
