Las corrientes y tensiones se expresan en su valor eficaz. Esta ventana representa el comportamiento de campos lejanos y cercanos. El diagrama de campos de campos lejanos se representa por defecto en coordenadas polares. Para que el usuario pueda optimizar y evaluar funciones, el modelo debe tener al menos una variable para optimizar. Se hace de la siguiente forma: Una vez dentro de la vantana Main, en Settings, marcamos Geometry Edit.

Zulkijas Once the geometry of the antenna is defined, number the wires, identifying also their diameter Dh i and their length Lh i. We will name Ns the number of segments making up a wire. This view enables detailed 3D analysis of antenna pattern, in the context of the antenna placement, for understanding peaks, nulls, and all aspects of complex far field propagation.

The original nec2c is a non-interactive command-line application that reads standard NEC2 input files and produces an output file with data requested by "commands" in the input file. In contrast xnec2c is a GUI interactive application that in its current form reads NEC2 input files but presents output data in graphical form, e. These results are only calculated and drawn on user demand via menu items or buttons, e. Printing of results to an output file has been removed starting from version 1. If printing to file is needed then it is better to use the original NEC2 program, to avoid bugs that may still be lurking in the C translation. Xnec2c now has a built-in editor for NEC2 input files which can be used to edit geometry or command "card" data.
