We intend to use the transfer matrix representation to calculate the local absorbed energy density as a function of space. This way multiple reflections and interferences in thin films, different incident angles and polarizations, s & p, are considered. The description of the formulas and the way we are implementing them can be found here: Description
The TMM_abs.py file works as function library and the Cobalt_example.py is a file which gives an example on how to use the code.
| Platinum | 3nm layer | n = 1.0433 + i3.0855 |
|---|---|---|
| Cobalt | 15nm layer | n = 1.0454 + i3.2169 |
| Chromium | 5nm layer | n = 2.0150 + i2.8488 |
| Magnesium Oxide | semi inf- layer | n = 1.7660 |
As absorption has units (power/volume), the profile in the plot, which has been normalized with respect to the light power density on the material (power/area), is given in units (1/length).
The angle is given from the surface normal. (0° is perpendicular and 90° is grazing).
