Abstract: The development and the application of the Numerical Electromagnetic Code (NEC) - Method of Moments are described. NEC is based on a previous method of moments code for thin wires, the Antenna Modeling Program (AMP), and yields improved estimates of the performance of antennas mounted on shore stations, ships, aircraft, and spacecraft. Wire Antenna Modelling with NEC-2 1 Numerical Electromagnetics Code (NEC) The software Numerical Electromagnetics Code (NEC-2) has been developed in the s in the Lawrence Livermore Laboratory in Livermore, California.

1. Introduction. Electromagnetic scattering by particles is a field of active research with high relevance for such diverse fields as atmospheric science, oceanography, astronomy, and engineering sciences, with specific applications in remote sensing, meteorology, ocean optics, climate research, scattering by interplanetary dust grains, bio-optical imaging, antenna theory, particle sizing Cited by: The Numerical Electromagnetics Code (NEC-1) is a computer code for analyzing the electromagnetic response of an arbitrary structure consisting of wires and surfaces in free space or over a ground plane. The analysis is accomplished by the numerical solution of integral equations for induced currents.
Abstract: The Numerical Electromagnetic Code (NEC-2) is applied to the electromagnetic analysis of tall structures hit by lightning. The advantage of the analysis using NEC-2 is that it can accurately compute the current distribution along a conductor system by the method of by: Developing and using numerical methods in a powerful tool for students to learn the principles of intermediate and advanced electromagnetics. This book fills the missing space of current textbooks that either lack depth on key topics (particularly integral equations and the method of moments) and where the treatment is not accessible to Author: Karl F.

The first edition of Numerical Techniques in Electromagnetics filled that gap and became the reference of choice for thousands of engineers, researchers, and students.
This third edition of the bestselling text reflects the continuing increase in awareness and use of numerical techniques and incorporates advances and refinements made in recent by: 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).Cited by: 4. NEC (Numerical Electromagnetic Code), written by Gerald Burke, is a popular antenna modeling code for wire and surface antennas and scatterers. Models can include wires buried in a homogeneous ground, insulated wires and impedance loads.
1 Introduction. The Numerical Electromagnetics Code (NEC) is a user-oriented computer code for the analysis of the electromagnetic response of antennas and other metal structures.
It is built around the numerical solution of integral equations for the currents induced on the structure by. The numerical approximation of Maxwell's equations, Computational Electromagnetics (CEM), has emerged as a crucial enabling technology for radio-frequency, microwave and wireless engineering.
The three most popular 'full-wave' methods - the Finite Difference Time Domain Method, the Method of Moments, and the Finite Element Method - are.
The Numerical Electmrnagnetics Code (ATEC) – Method of Moments is a computer program for analyzing the electromagnetic response of antennas and scatterem. The oode is based on the numerical solution of integral equations by the method of moments, and combines an electric-field integral equation for modeling thin wires with a magnetic-fieldFile Size: 9MB.

Moved the geometry parsing to a separate file. Will move to PCCTS, and an API for specifying. The author also added a chapter on the method of lines.
Numerical Techniques in Electromagnetics continues to teach readers how to pose, numerically analyze, and solve EM problems, give them the ability to expand their problem-solving skills using a variety of methods, and prepare them for research in electromagnetism.5/5(2). The Numerical Electromagnetics Code, or NEC, is a popular antenna modeling system for wire and surface antennas.
It was originally written in FORTRAN in the s by Gerald Burke and Andrew Poggio of the Lawrence Livermore National Laboratory. The code was made publicly available for general use and has subsequently been distributed for many computer platforms from mainframes to PCs.
