==== U-Shaped System Electric Field Intensity (USSEFI) ====
----
U-Shaped System is a simple type of electric fields utility. It includes a pair of insulated plate electrodes
and the homogeneous dielectric material between the electrodes. Therefore, the system have only two kinds of
dielectrics, i.e., two insulating layers and a homogeneous dielectric.
