Effect of grid spacing on the inductance of ground grids
IEEE 1991 International Symposium on Electromagnetic Compatibility, 2002The effect of grid spacing on the inductances of various paths on a printed circuit board (PCB) is investigated numerically. Partial inductances of the various segments of the paths and the ground grid are incorporated into a lumped model which is solved for the currents using the mesh current method.

Nonuniform Semi-Infinite Grounded Grids
SIAM Journal on Mathematical Analysis, 1982Semi-infinite resistive grounded grids are countably infinite electrical networks that arise from the discretization of the partial differential equation governing the minority-carrier density in a doped semiconductor. If the doping varies with depth from the surface of the semiconductor, the grid’s resistances also vary with distance from the inputs ...

IEEE Transactions on Magnetics, 2006
In this paper, we present how the finite element method (FEM) can be utilized to analyze the influence of an additional substance in the trenches surrounding the grounding grid's conductors on the grounding grid's performance. For this purpose, we modified the preliminarily existent FIELD_GS program code in such a way that the additional substance in ...

Analysis of the Ground Impedance of Ground Grids Combined with the Carbon Ground Electrodes
Journal of the Korean Institute of Illuminating and Electrical Installation Engineers, 2013This paper deals with the frequency-dependent ground impedance of ground grids combined with the carbon ground electrodes. Ground grids are generally valid for multipurpose grounding systems as well as lightning protection systems. The carbon ground electrodes may be supplementarily used to reduce the high frequency ground impedance and to improve the ...
