Numerical Electromagnetic Code (NEC)-Basic Scattering Code. Part I. User's Manual.
Abstract
The Numerical Electromagnetic Code - Basic Scattering Code is a user-oriented computed code for the analysis of the far field patterns of antennas in the presence of perfectly conducting metal structures at UHF and above. The analysis is based on uniform asymptotic techniques formulated in terms of the Geometrical Theory of Diffraction (GTD). Complicated structures can be simulated by arbitrarily oriented flat plates, an infinite ground plane, and a finite elliptic cylinder. A wide range of practical problems can be simulated using these shapes. For example, flat plates can be used to model the superstructure of a ship, the body of a truck, or the wings and stores of an aircraft. The finite elliptic cylinder can be used to model a mast or smoke stack of a ship, or the fuselage and engines of an aircraft. This document is designed to give an overall view of the operation of the computer code, to instruct a user in how to model structures, and to show the validity of the code by comparing various computed results against measured data whenever available. It, also describes in detail the input and output data for the code. This information should be sufficient for most user's to learn how to effectively operate the code. (Author)
