Hi,
I'm using vasp.5.3.5 and having problem when calculating dielectric constant with spin-orbit coupling. While the band structure w/ spin-orbit is almost identical to that w/o spin-orbit. The dielectrics are completely different.

Any explanation for the difference?

Thanks

To calculate epsilon I use:
LOPTICS = T
LRPA = T

for spin-orbit calculation I add:
LSORBIT = T

The link below is the imaginary part of epsilon.
