Hi

I calculate the bulk Au by set LEPSILON=T,

I got

MACROSCOPIC STATIC DIELECTRIC TENSOR (including local field effects in DFT)
-------------------------------------
8.129 0.000 0.000
0.000 8.129 0.000
0.000 0.000 8.129
-------------------------------------



dose the real dielectric constant for metal should be very huge?
what's the meaning of the value 8.129 here?

Thanks
