Uniform Asymptotics of the Pseudo Wigner-Ville Distribution for Nonlinear Chirps
Vincenzo Pierro, Maurizio Feo, Maurizio Ricciardi +4
The analysis of non stationary signals in complex physical systems often relies on Time Frequency distributions. Among these, the Pseudo Wigner Ville Distribution (PWVD) stands out…

Planar near-field antenna measurements with a uniform step larger than half-wavelength
Raffaele Moretta, Fabio Pascariello, Giovanni Petraglia +2
In this paper, a new sampling scheme of the near field radiated by a planar source is proposed and assessed. More in detail, the paper shows a uniform sampling criterion that allow…

Transformation-Optics-Based Design of a Metamaterial Radome for Extending the Scanning Angle of a Phased Array Antenna
Massimo Moccia, Giuseppe Castaldi, Giuliana D'Alterio +3
We apply the transformation-optics approach to the design of a metamaterial radome that can extend the scanning angle of a phased-array antenna. For moderate enhancement of the sca…
