Abstract :
Four different methods are examined to evaluate the potential due to a half-line source in a homogeneous space. The derivatives of the potential, which are needed to calculate the fields, are also treated. All four methods are compared in terms of accuracy and computational cost in order to determine the most efficient among them for each region of space. The gradient of the potential is also examined.
