Superbackscattering Antenna Arrays [PDF]
IEEE Transactions on Antennas and Propagation, 2015 This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering cross-section, normalized to the wavelength squared, of a linear array of N isotropic scatterers whose separation tends to zero is N2(N + 1 ...

The Method of Maximum Power Transmission Efficiency for the Design of Antenna Arrays
IEEE Open Journal of Antennas and Propagation, 2021 Various methods have been proposed to control the electromagnetic fields in the near-or far-field region, one of which is to use antenna arrays. This paper reviews a technique, called the method of maximum power transmission efficiency (MMPTE), for the ...
