TL;DR: In this paper, the human body was modeled by a cylindrical scatterer placed vertically on the perfect conducting ground. And the results of the radiated fields were incorporated in the numerical calculations as an incident field.

TL;DR: In this article, a numerical-stochastic technique for an optimisation of underground cable systems is based on a finite element mesh generator carried out by means of the advancing front method, a nonlinear coupled electric-thermal model, a multiquadric ampacity approximations including successive zooming steps, and a stochastic optimisation method involving differential evolution.

TL;DR: In this article, the direct time domain calculation of a transient electric field generated by a ground penetrating radar (GPR) dipole antenna and transmitted into the lossy half-space is discussed.

TL;DR: In this article, the authors deal with two different approaches to the assessment of the transient impedance of a horizontal grounding electrode: frequency domain boundary element analysis, based on the straight thin wire antenna model (AM) and generalized telegrapher's equations combined with inverse Fast Fourier Transform (FFT), and time domain finite element analysis based on transmission line model (TLM) and standard TElegraphers equations.

TL;DR: In this paper, a simple model of a dipole antenna radiating above a layered medium is presented, where the influence of the earth-air interface is taken into account via the simplified reflection coefficient arising from the Modified Image Theory (MIT).
