To help to remove air from my rolled capacitor (to be built) I was thinking to
use paper and PE as dielectric. That is

---- Al
---- paper
---- PE
---- Al
---- paper
---- PE

Now the difficult question: if I use as dielectric two materials together,
say:

- material A, thickness tA, dielectric constant kA, dielectrict strength vA
- material B, thickness tB, dielectric constant kB, dielectrict strength vB

what is going to be the resulting dielectric constant? And the dielectric
strength?
