Title: Pseudo- High Order Wire Antenna Solvers

Abstract: We discuss our recent work concerning the evaluation of the current induced on thin wire antenna structures either by an incident field (the receive problem) or by a source located on the wire (the transmit problem). Our previous methods have been extended to accommodate arbitrarily large arrays of non-intersecting wire segments with a current source located on an array element. We also discuss our recent work in computational methods to accurately model the current in a neighbourhood of the source -- a long-standing difficulty in wire antenna modeling. We illustrate the performance of our solvers by considering an array of several hundred wire elements. Near and far-field results are efficiently extracted along with other quantities of interest such as the antenna gain. With Oscar Bruno, Caltech.
