ABSTRACT

Abstract:

The FDTD method ahs been used extensively in electromagnetic field modeling because of its ability to robustly handle interactions of fields with complex heterogenous structures. In particular, the total/scattered field formulation has allowed for efficient implementation of arbitrarily directed uniform plane wave, consequently facilitating efficient modeling of far-field scattering problems. The total/scattered approach is not restricted to plane waves and can be expanded to any waveforms that can be described in analytical or semi-analytical form. One such situation of interest to the utility industry to be modeled is the case of workers in the near-field of high voltage powerlines, where the field is non-uniform.

In this seminar, the fundamentals of the FDTD will be outlined, as well as the theory and implementation of equivalent sources via the total/scattered field formulation using plane waves. Also, some preliminary thesis work to augment the total/scattered field formulation to allow for the near-field line-source configuration will be presented.

Note: Another seminar detailing the thesis work - extension of the method to spherical wave sources - will be presented on the following Tuesday at 2pm.

Questions or concerns can be put to,
