A Novel Methodology for Gain Enhancement of the Fabry-Pérot Antenna
IEEE Access, 2019 A significant problem that is encountered with the traditional Fabry-Pérot cavity (FPC) antenna is the nonuniform phase distribution inside the cavity, which adversely affects the radiation characteristics of the antenna.

Generalizing the Coleman-Hill Theorem [PDF]
, 1995 Following the work of Khare {\it et al}, we show that the generalization to systems with spontaneous symmetry breaking of the Coleman-Hill theorem to one-loop order, can be extended to the case including fermions with the most general interactions ...

Ray Theory-Based Transcranial Phase Correction for Intracranial Imaging: A Phantom Study
IEEE Access, 2019 Ultrasonic imaging provides a non-invasive way to diagnose brain disease. However, due to imaging degradation effects from the phase-aberration and reverberation, it is still challenging to achieve an accurate transcranial imaging.

Second-order phase correction of NMR spectra acquired using linear frequency-sweeps
Magnetic Resonance Letters, 2022 NMR spectra acquired with experiments using frequency-sweeps such as the wide-band uniform-rate smooth truncation (WURST) spin-echo and Carr-Purcell-Meiboom-Gill (CPMG) sequences cannot be absorptively phased by using only conventional zeroth- and first ...

Compensation for phase distortions in nonlinear media by phase conjugation [PDF]
, 1980 We demonstrate theoretically that the distortion-correction property of phase-conjugate beams propagating in reverse through aberrating media is also operative when the indices of refraction of the media depend on the intensity.

Maximum Kurtosis Phase Correction [PDF]
Geophysical Journal International, 1988 Summary Seismic reflectivity sequences have amplitude distributions that are leptokurtic, that is, they are more heavy-tailed than a Gaussian distribution. This property forms the basis of a method of phase adjustment for seismic reflection data, called maximum kurtosis phase correction (MKPC), that maximizes the ‘stand-out’ of events on seismic ...

CORRECTIONS TO TRIBIMAXIMAL MIXING FROM NONDEGENERATE PHASES [PDF]
Modern Physics Letters A, 2010 We propose a seesaw scenario that possible corrections to the tribimaximal pattern of lepton mixing are due to the small phase splitting of the right-handed neutrino mass matrix. We show that the small deviations can be expressed analytically in terms of two splitting parameters (δ1 and δ2) in the leading order.
