Abstract :
This paper will consider a case for a dipole immersed in a lossy dielectric medium. Previous research has yielded relatively complex non-closed form formulae that still need numerical computation. Here we consider the simplification of the analysis of near field exposure although the analysis converges in the far field region. The usefulness of the closed-form formulae are verified through comparison with simulation results from a Method of Moments solver and then implemented in MATLAB to enable further analysis. The overall accuracy was better than 11% overall in terms of normalized root mean square error.
