COSMO : a new approach to dielectric screening in solvents with explicit expressions for the screening energy and its gradient

, 1993
Starting from the screening in conductors, an algorithm for the accurate calculation of dielectric screening effects in solvents is presented, which leads to rather simple explicit expressions for the screening energy and its analytic gradient with ...

Scattering by dielectric circular cylinders in a dielectric slab

Journal of the Optical Society of America A, 2010
An 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 ...

DIELECTRICS

2000
This chapter deals with the definition of the basic concepts such as bioimpedance, bioelectricity, conductor, dielectric, and so on. It gives examples of active and passive electrical properties of biomaterials and also provides an overview of what is covered in the rest of the book.

Optimization of the dielectric layer for electrowetting on dielectric

Integration, 2019
Abstract In this work the minimum actuation voltage Vmin for droplet actuation with electrowetting on dielectric (EWOD) is analyzed. At first, the theoretical background of drop transport with EWOD is shown. Then the impact of thin dielectric films deposited with atomic layer deposition (ALD) and super-hydrophobic layers on the minimum required ...

Non-symmetrical dielectric relaxation behaviour arising from a simple empirical decay function

, 1970
The 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, 1986
A 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 ...
