Hi Amrita,

it seems that i have finally out the main culprit to my problem earlier. I was using METAL BC instead of PML.

So, when i ran PML, i finally gotten the proper loss readings.

But i was wondering, some of the modes showed a NEGATIVE loss. 

Does this means, there is an error in the calculation/design somewhere or perhaps the material does show negative loss on certain modes?

thanks for your help.
