Thank you @Sagar for the reply.


In addition to the periodic BCs, please sweep the heights to get the transmission maps in the paper.


From your result, it is for one height, and the frequency points are only 5 I believe, then you will not be able to get results similar to the reference.


In addition you may need to read the example carefully to understand the settings and resuult.

Please also refer to this post as the comparison might not be very straight forward:
