Electromagnetic Near-Field Computations for a Broadcast Monopole Using Numerical Electromagnetics Code (NEC).

Abstract

An often ignored aspect of electromagnetic radiation from antennas is the characterization of their near-fields. A computer program, Numerical Electromagnetics Code, is validated for accurate near-field computations and applied to a model of a broadcast monopole. E- and H-fields are plotted as a function of position along the antenna for various distances from the surface. The fields are also plotted as a function of radical distance outward for various heights. (Author)
