Space and surface charge excitation of a slanted dielectric interface between two electrodes
The two-dimensional, electrostatic problem of a planar dielectric interface between two perfectly conducting plates has been solved numerically. The solution allows for an arbitrary interface angle relative to the plates as well as arbitrary distributions of both charge within the volume and surface charge along the interface. The problem is treated by first converting the governing differential equations to a pair of coupled integral equations using Green's function techniques, then solving these integral equations numerically using moment methods. This report details this solution and shows some sample results. This work was motivated by the need to understand the physics of dielectric breakdown by flashover in high voltage insulator applications. Of particular interest is the physics associated with Magnetic Flashover Inhibition (MFI), a possible method of significantly increasing insulator breakdown strength above that possible using currently proven technologies. A solution of this type has several apparent advantages over existing techniques for treating this type of problem and is currently being adapted for use in an existing two-dimensional Particle-In-Cell (PIC) code.
