Our capacitor has two dielectrics in series, the first one of thickness (d_1) and permittivity (epsilon_1) and the second one of thickness (d_2) and permittivity (epsilon_2). As always, the thicknesses of the dielectrics are supposed to be small so that the fields within them are uniform. This is effectively two capacitors in series ...
