This example shows how to add holes to your structure and can be reproduced with examples/phononic_crystal.py
input file. The structure contains the square array of holes defined in the input file as:
Here, the HOLES
list is filled with the CircularHole
objects. This will create a structure that looks like so:
If we increase the number of phonons to several thousand, we can see some interesting distributions, for example the distributions of phonon angle at the beginning (red) and end (blue) of the structure. Interestingly, the array of holes "aligned" phonon trajectories along the passages between the holes [1, 2].
One can also output, for example, phonon frequency spectrum or time phonons took to reach the cold side.
The file information.txt
also contains various statistical insides, for example, the scattering likelihood:
