Abstract:

The Interactive Graphics Utility for Army NEC Automation IGUANA is a system designed to reduce the time required for antenna model evaluation by providing partial automation to both the data entry and the data display processes. Previous to this system, the use of existing Numerical Electromagnetics Code NEC for antenna evaluation required a lengthy, tedious, and error-prone process involving manual measurement of three-dimensional coordinates of each significant point of the desired input structure from scale drawings generally, only top and side views are available, and manual entry via keyboard. The input structures are in the form of wire models. The NEC code requires that each wire be specified individually by defining the x, y, and z coordinates of both end points, the wire radius, and the segmentation for each wire. Complex models often required several weeks of effort to specify, check, and to correct measurement and keyboard errors. IGUANA has been developed as an aid to NEC input preparation and output display - it performs no antenna evaluations itself. This version of IGUANA produces input acceptable only for the NEC Method of Moments code.
