Negative transmittance in comsol

Please login with a confirmed email address before reporting spam

Hello everyone

I am simulating a model for periodic silver sphere for in-plane and out-plane polarization. But when i am plotting the transmittance in case of in-polarization with angle of incident 50 deg then it gives me transmittance value greater than 1 while it is giving the correct value of out-plane polarization even also it is giving correct value of transmittance for angle less than 50 deg in in plane also.

I don't know why it is happening ?
If anyone have any suggestion please help me.

Thanks
