A multi-domain theory, however, has pointed out the importance of microscopic parameters, such as the domain wall energy coupling constant, and it helped explain the somewhat contradicting experiments for ferroelectric capacitors with or without a metal interlayer. In this work we use comprehensive numerical simulations and simplified equations
The acoustic microscope has been shown to be a powerful new tool for characterizing nondestructively the internal structure of multilayer ceramic capacitors. Delamination resolution has been shown to be greater than is available with other current techniques.

I use two different 33 uF MKP capacitors in series to make 16.5 uF. One is a DIYaudio Silver cap and the other an old Solen Chataeu Rough(?)

However, the case of capacitors is peculiar due to two main technical difficulties: first, electrochemical boundary conditions should be introduced for the electrodes; second, the interactions at the interface between the electrode and the electrolyte (Figure 4 C) need special care. Figure 4.
Conventional capacitors involve two metallic plates facing each other and separated by a dielectric medium. Opposite charges are accumulated on the two electrodes, and the energy stored is proportional to its capacitance C, which follows the relation
