Multi-pole multi-zero frequency-independent phase-shifter
M. A. Bitar, A. Gallo, F. A. Volpe
A multi-pole, multi-zero design allowed realizing a "true" phase-shifter (not time-delayer) of flat frequency-response over more than 3 decades (30Hz-100kHz), which can be extended…

Reverse Chromatic Aberration and its Numerical Optimization in a Metamaterial Lens
W. J. Capecchi, N. Behdad, F. A. Volpe
In planar metamaterial lenses, the focal point moves with the frequency. Here it is shown numerically that this movement can be controlled by properly engineering the dimensions of…

Oblique electron-cyclotron-emission radial and phase detector of rotating magnetic islands applied to alignment and modulation of electron-cyclotron-current-drive for neoclassical tearing mode stabilization
F. Volpe, M. E. Austin, G. Campbell +1
A two channel oblique electron cyclotron emission (ECE) radiometer was installed on the DIII-D tokamak and interfaced to 4 gyrotrons. Oblique ECE was used to toroidally and radiall…
