Scattering by dielectric circular cylinders in a dielectric slab
Journal of the Optical Society of America A, 2010An analytical-numerical technique for the solution of the plane-wave scattering problem by a set of dielectric cylinders embedded in a dielectric slab is presented. Scattered fields are expressed by means of expansions into cylindrical functions, and the concept of plane-wave spectrum of a cylindrical function is employed to define reflection and ...

Non-symmetrical dielectric relaxation behaviour arising from a simple empirical decay function
, 1970The empirical dielectric decay function γ(t)= exp –(t/τ0)β may be transformed analytically to give the frequency dependent complex dielectric constant if β is chosen to be 0.50.

Dielectric Breakdown in Solid Dielectrics
IEEE Transactions on Electrical Insulation, 1986A review is presented on Japanese research on the fundamental dielectric breakdown of solid dielectrics. First, the theoretical consideration on the basic breakdown process and the experimental work on pre-breakdown phenomena are described. Secondly, described is the space charge effect on the dielectric breakdown, the importance of which was realized ...

Dielectric nanocomposite with high dielectric permittivity and low dielectric loss
2015 IEEE Electrical Insulation Conference (EIC), 2015Dielectric flexible nanocomposites featuring ferroelectric barium titanate nanoparticles embedded in poly(vinylidene fluoride) (PVDF) matrix were fabricated by a miscible-immiscible coagulation method followed by hot pressing. The SEM images showed good distribution of nanoparticles with very little particle agglomeration.
