Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Wireless communications have demand for wireless device of light weight, small size, having low energy consumption and of more practicability. The microstrip antenna is the best choice that fulfills the basic requirements of wireless communication device i.e. antenna should be relatively cheap, light weight, robust, easy to manufacture and with a minimum impact on environment. The microstrip patch antennas are of narrow band width because of which the design parameters of patch antenna must be determined with high precision. So, with in a fabrication process of such kind of antennas, Artificial Neural Networks (ANNs) based models trained with experimental/generated data of same class, previously collected, can preliminary estimate the design parameters, reducing the number of real prototypes to be constructed, saving time and resource. The results obtained using, Artificial Neural Networks (ANN) techniques are close to experimental results and Electromagnetic computer (EMC) simulating tools. Therefore to design Microstrip patch antennas for wireless communication, Artificial Neural Network techniques can be embedded in computer aided design (CAD) system.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - There are always more aspects that can be investigated than what is presented. Here also, there are some aspects of both the new antenna and parameter calculation that can be extended. The new designed presented in this thesis open up the scopes for high gain, wide band and miniaturized microstrip patch antennas for wireless applications. The controlling tools like slot length, width, angle can be further exploited to achieve tunable parameters of micros trip patch antenna as required in application like medical imaging, cancer detection and smart wireless environment. The idea of implementing artificial neural networks in parameters calculation of microstrip patch antenna invites further exploration of the technique to reduce the complexities in the antenna design and analysis. Integration with optimization techniques such as Genetic algorithm, PSO etc may enhance the efficiency in terms of computational time and accuracy to make the ANN method of antenna design more acceptable especially for the application areas like bio-medical and smart wireless environment.…

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - From this book it has been also observed that the methods solves for the field sources (currents and charges). These sources can be either physical sources, or mathematical (equivalent) sources introduced through various electromagnetic field theorems. In the numerical analysis, the electromagnetic fields, or the related potentials, are expressed in terms of these sources, usually through the Lorentz potentials. The expressions are integral forms, where the sources appear under some integrals, multiplied by appropriate functions, which are referred to as kernels. For example, for fields in a vacuum, the kernel for the Lorentz potentials is the free-space Green's function. On the other hand, certain equations are imposed based on the boundary conditions or constitutive relations. The boundary conditions relate tangential and normal components of the field vectors at a surface of discontinuity. For example, on the surface of a perfectly conducing body, the tangential component of the electric field vanishes.…

Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - De este libro también se ha observado que los métodos resuelven las fuentes de campo (corrientes y cargas). Estas fuentes pueden ser fuentes físicas, o fuentes matemáticas (equivalentes) introducidas a través de varios teoremas de campo electromagnético. En el análisis numérico, los campos electromagnéticos, o los potenciales relacionados, se expresan en términos de estas fuentes, normalmente a través de los potenciales de Lorentz. Las expresiones son formas integrales, donde las fuentes aparecen bajo unas integrales, multiplicadas por funciones apropiadas, que se denominan kernels. Por ejemplo, para los campos en el vacío, el núcleo de los potenciales de Lorentz es la función de Green del espacio libre. Por otro lado, se imponen ciertas ecuaciones basadas en las condiciones de contorno o relaciones constitutivas. Las condiciones de contorno relacionan las componentes tangenciales y normales de los vectores de campo en una superficie de discontinuidad. Por ejemplo, en la superficie de un cuerpo perfectamente conductor, la componente tangencial del campo eléctrico desaparece.…

Queste fonti possono essere sia fonti fisiche, sia fonti matematiche (equivalenti) introdotte attraverso vari teoremi del campo elettromagnetico. Nell'analisi numerica, i campi elettromagnetici, o i relativi potenziali, sono espressi in termini di queste fonti, di solito attraverso i potenziali di Lorentz. Le espressioni sono forme integrali, dove le sorgenti appaiono sotto alcuni integrali, moltiplicati per funzioni appropriate, che vengono chiamate kernel. Per esempio, per i campi nel vuoto, il kernel per i potenziali di Lorentz è la funzione di Green dello spazio libero. D'altra parte, alcune equazioni sono imposte in base alle condizioni al contorno o alle relazioni costitutive. Le condizioni al contorno mettono in relazione le componenti tangenziali e normali dei vettori di campo su una superficie di discontinuità. Per esempio, sulla superficie di un corpo perfettamente conduttore, la componente tangenziale del campo elettrico svanisce.…
