Hello , I have installed the 32bits version of OPTIFDTD and design a subwavelength hole periodic structure ,
and settings are based on lesson 15 of 32bits_tutorial.pdf except the script part.
According to the tutorial I would like to calculate the power transmission spectrum , but the result shows some value is higher than 1 ,
even normalize to the input plane .
After tuning the input plane setting , mesh , time interval , even the APML boundary condition ( though I don’t quite know the meaning of tensor parameter and grading polynomial ) , but I can’t have the result that power transmission spectrum lower than 1.
After that I have read the forum and search for some answer and found someone had the same question but no clear setting can be found.
I upload the design file and hope I can have some help here , thank you very much.
.
