Fundamentos de Aplicaciones en Electromagnetismo | 6ta Edición | Fawwaz T. Ulaby Gratis en Descarga Directa
- Las líneas de transmisión constituyen un puente natural entre los circuitos eléctricos y electromagnéticos. Mediante la introducción de líneas de transmisión temprana, Ulaby permite al estudiante utilizar conceptos familiares para aprender acerca de muchas de las propiedades de propagación de las ondas en una estructura de guiado.
- Breves Tecnología conectan un concepto básico, como capacitancia, inductancia, o la polarización, para aplicaciones del mundo real.
- El CD-ROM interactivo que acompañan el texto se puede utilizar en conjunción con el material en el libro de texto de auto-estudio. Las funciones para múltiples ventanas de las pantallas electrónicas hacen posible el diseño de módulos interactivos, con los botones de “ayuda” para guiar al estudiante a través de la solución de un problema cuando es necesario. Animaciones de vídeo pueden mostrar cómo los campos y las ondas se propagan en el tiempo y en el espacio, ¿cómo se puede hacer el haz de una red de antenas para escanear electrónicamente, y ejemplos de cómo se induce corriente en un circuito bajo la influencia de un campo magnético variable.
- Se hace hincapié en el uso de las matemáticas para explicar y aclarar la física, seguida de ejemplos prácticos destinados a demostrar la relevancia de ingeniería de los conceptos físicos
Nuevo en esta edición
- Un conjunto de 42 módulos de simulación de CD interactivos que permiten al usuario a los circuitos de línea de transmisión de diseño analizar de forma interactiva y; generar patrones espaciales de los campos eléctricos y magnéticos inducidos por cargas y corrientes; visualizar en 2-D y en el espacio 3-D como el gradiente, divergencia, y el rizo de operar sobre las funciones espaciales; observar las formas de onda temporal y espacial de ondas planas que se propagan en medios sin pérdidas y con pérdidas; calcular y mostrar las distribuciones de campo dentro de una guía de onda rectangular; y generar diagramas de radiación de antenas lineales y platos parabólicos.
