Dataset for modelling studies presented in 'Ultra-high discharged energy density capacitor using high aspect ratio Na0.5Bi0.5TiO3 nanofibers'

Data obtained from 2D finite element electrostatic model of a single high permittivity inclusion within a low permittivity matrix. The angle and aspect ratio of the inclusion has been varied and the local electric field in each element recorded and stored in the raw data files. Permittivity is recorded for each structure.

A compiled dataset is also included on the study of the effect of an interfacial layer between the high permittivity inclusion and low permittivity matrix on the electric field distribution within the composite. In this case the maximum field concentration within the matrix and the interfacial layer are recorded alongside the permittivity for varying interlayer thickness.
