The paper deals with analytical and numerical modeling of vertical straight thin wire above a lossy ground. The analysis is based on the solution of the corresponding Pocklington integro-differential equation. The numerical solution is carried out via the Galerkin-Bubnov Indirect Boundary Element Method (GB-IBEM). Some illustrative computational examples are presented in the paper. Obtained numerical...
The paper deals with transient analysis of ring shaped grounding electrodes using isoperametric quadratic elements. The formulation in the frequency domain is based on the thin wire antenna theory and the related Pocklington integro-differential equation while the corresponding transient response is obtained by means of the Inverse Fourier Transform (IFT). The Pocklington integro-differential equation...
The paper deals with FEKO and SuzANA simulations of time-harmonic and transient phenomena on transmission lines above perfectly conductive ground plane and real ground plane, respectively. The influence of transmission line length, height above ground and ground electrical parameters to transmission line transient response have been analyzed throughout these simulations. Time harmonic and transient...
The paper deals with the three dimensional modelling of the human body exposed to extremely low frequency (ELF) high voltage electric fields by mean of the boundary element method (BEM). Numerical results along head, neck, torso, abdomen, arms, legs and ankles are presented and discussed in the case of grounded subject standing under power distribution lines. The objective is to characterise the influence...
In this paper a cylindrical model of human body exposed to the extremely low frequency (ELF) electromagnetic field is presented. The analysis is based on the solution of the simplified integral equation for thick wires. The numerical solution of the integral equations is performed by the Galerkin-Bubnov variant of the boundary element method. Several numerical results for the ELF exposures are presented.
