Abstract

This paper presents a method of moments (MoM) solution to the problem of a wire attached to an arbitrary faceted surface by developing a special attachment basis function, which enforces continuity of current at the wire/plate junction and also models the nearly singular-plate surface-current density in the vicinity of the attachment point. This new attachment mode contains a nonplanar disk, which conforms to the faceted surface in the vicinity of the attachment point and has current that spreads uniformly from the attachment point. It is applicable near or at the edges and corners of the facets
