Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This book addresses the analysis and design of reconfigurable metamaterial (MM). MM is an artificial material with negative permittivity, and permeability over the same frequency band. It has special characteristics not found in the natural material, so it can be used to enhance the antenna characteristics such as gain, bandwidth, and manipulate the polarization of the wave. The requirements for increased functionality within a confined volume placed a greater burden on today's transmitting and receiving systems. Reconfigurable antennas are a solution to this problem. Reconfiguring an antenna is achieved by changing its frequency of operation, polarization, or radiation characteristics. This change is achieved by many techniques that redistribute the antenna currents and thus alter the electromagnetic fields of the antenna's effective aperture. This concept can significantly reduce the number of components and thus hardware complexity, and cost of communication systems. Different materials are investigated in MM surfaces as water, plasma, copper, and graphene.…
