Soft cover. Condition: New. Sundarban is the last remaining largest mangrove forest of the world with rich ecosystem and immense diversity, spread over 10,200 sqm. across the delta of the river Ganges, Brahmaputra and Meghna on the Bay of Bengal. The mangrove ecosystem of Sundarban is the home to diverse types of aquuuuuuand terrestrial plants and animals. Butterflies being important part in the foold chain act as a source of food for various predators and an important media of plangt pollination. In the recent years butterflies are considered as a focal species for biodiversity coservation in different parts of the world.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Experimental investigations of rectangular, circular and elliptical microstrip patch antennas are reported in this book. An analytical method of controlling the input impedance of different patch antennas as a function of feed location is presented here. Using different kind of reference antennas (rectangular, circular, elliptical) the variation of input impedances, both the real and imaginary components, while changing the feed positions is compared with the theoretical results. At the same time various antenna properties like return loss, input impedance, gain and radiation efficiency are calculated with the proposed model and compared with the simulated results. The results due to different type of patches are compared. 56 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The book focuses on the basics of a number of evolutionary algorithms for electromagnetic optimization instances. It includes conventional optimization strategies like simulated annealing, particle swarm optimization, differential evolution along with their improved variants. Moreover, the text introduces several recently developed nature inspired metaheuristic algorithms like artificial bees colony optimization, fire fly algorithm and gravitational search algorithm. The book reviews the effect of mutual coupling on the operation of different array geometry using induced EMF technique. It presents a rigorous analysis of linear array antennas of half wave dipoles and optimizes the radiation characteristics of non-uniformly spaced and non-uniformly excited linear array of parallel and collinear dipoles considering mutual coupling using evolutionary algorithms: Particle Swarm Optimization and Differential Evolution. Coupling effect between the elements and analyzed using induced EMF method and minimized in terms of SWR. Numerical results obtained from both the algorithms are proved highly efficient and statistically compared to present a comprehensive overview. 72 pp. Englisch.
