Dielectric filling into capacitor

27. CAPACITORS AND DIELECTRICS.

Since [kappa] is larger than 1, the capacitance of a capacitor can be significantly increased by filling the space between the capacitor plates with a dielectric with a large [kappa]. The electric field between the two capacitor plates is the vector sum of the fields generated by the charges on the capacitor and the field generated by the surface charges on the …

Along this line of thought, we intend to introduce voids, dielectric filler and conductive filler into the dielectric layer with controlled content and distribution. To achieve this, a "root" like dendritic colloidal polyurethane (DCPU) was prepared to grab a large number of carbon nanotubes (CNT) and barium titanate (BaTiO 3, BT) forming hybrid filler.

Gauss''s law is that the total (D)-flux arising from a charge is equal to the charge, so that in this geometry (D = sigma), and this is not altered by the nature of the dielectric materials between the plates. Thus, in this capacitor, (D = CV_0/A = Q/A) in both media. Thus (D) is continuous across the boundary.
