This produced the Antenna Modeling Program, or AMP, which was extensively modified to support disk-based files, simplify the input and output to make it easier to use, and extensively documented. A follow-up, AMP2, added calculations for extended surfaces like reflectors. [2] NEC is an advanced version of AMP2, with more options and features.
The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Code series published by the National Fire Protection Association (NFPA), a private trade association . [ 1 ]
The NEC also requires the high-leg conductor of a high-leg delta system to have orange insulation, or to be identified by other suitable means such as tagging. Prior to the adoption of orange as the suggested colour for the high-leg in the 1971 NEC, it was common practice in some areas to use red for this purpose. [14]
The latest versions of many European wiring regulations (e.g., BS 7671 in the UK) follow the section structure of IEC 60364 very closely, but contain additional language to cater for historic national practice and to simplify field use and determination of compliance by electricians and inspectors. National codes and site guides are meant to ...

Simulation of negative refraction from a metasurface at 15 GHz for different angles of incidence. The simulations are performed through the method of moments. The method of moments (MoM), also known as the moment method and method of weighted residuals, [1] is a numerical method in computational electromagnetics.
The report raised a litany of concerns and questions about how the Jan. 6 investigation was carried out, how witnesses may have been pressured or influenced, and how records, files and other ...
