Distance-selective wireless networks with enhanced isolation characteristics: a new concept based on three-dimensional wave field synthesis for volumetric-controlled field coverage

The paper introduces the concept of distance-selective wireless networks for volumetric-controlled field coverage, and discuss the possibility of employing three-dimensional wave field synthesis algorithms. A novel three-dimensional array is employed in which the elements face inwards, such that selected radiated field components can be reduced or enhanced within the desired volumetric coverage as a function of time. Preliminary results derived from conventional analysis techniques (Terada, M., URSI Int. Symp. on Electromagnetic Theory, 2004) are discussed, indicating the possibility of applying a formal wave field synthesis algorithm.
