Analysis of Transmission Loss and Boresight Error of a Curved FSS Radome-Enclosed Antenna
IEEE Access, 2021 In this paper, we numerically study a curved frequency selective surface (FSS) radome, which encloses a waveguide slot array antenna operating at 10GHz, using the ray tracing technique and flat model.

Extended low-frequency phase of the distortion-product otoacoustic emission in human newborns [PDF]
JASA Express Letters, 2021 At constant f2/f1 ratios, the phase of the nonlinear distortion component of the 2f1−f2 distortion-product otoacoustic emission (DPOAE) has a steep low-frequency segment and a flat high-frequency segment in adults and newborns.

Model-Free Lens Distortion Correction Based on Phase Analysis of Fringe-Patterns
Sensors, 2020 The existing lens correction methods deal with the distortion correction by one or more specific image distortion models. However, distortion determination may fail when an unsuitable model is used.
