Analysis of electric field in inclined dielectric media by heaviside unit-step function

It is so important to predict electric fields in advance before designing electrical devices or electronic products. In general, an electric field for an electric device to be designed is usually calculated using a commercial numerical analysis program. However, numerical analysis programs are very expensive, require high specifications for computers, and are also insufficient to have a physical understanding of the trends in electric fields. Therefore, in this paper, the electric field is obtained using the derived analytical equation using Heaviside unit-step function about the discontinuity of dielectric constants especially in the structure of the inclined dielectric media because of the discontinuity about the dielectric constants at the interface where two dielectric materials meet. Finally, the analytical method-based results are compared with the numerical analysis results and verified.
