Dear Amrita, 

thank you very much fr your answer! I will proceede to install the latest version to see if this problem gets fixed.

In the meantime I attach two pictures: one regarding the geometry and the other regarding the interfaces.

Basically the geometry consists of a substrate on top of which there is a waveguide layer and a grating on top of it.

To ease the design, the top interface of the substrate is at y=0 which also coincides with the bottom interface of the waveguide layer.

Also the thickness of the waveguide layer is 1.3613 um while the thickness of the grating is 0.1 um (in this case I’m considering the substrate as infinite).

 

Thank you in advance.

 

Regards
