—Micro-Doppler signatures from four CAD aircraft engine models and one experimental engine model are analyzed using joint time-frequency analysis (JTFA). The signatures are obtained from shooting and bouncing rays (SBR) simulation for the CAD models and from measurement for the experimental model. The JTFA results give additional useful physical feature(More)
The Rashba effect is one of the most striking manifestations of spin-orbit coupling in solids and provides a cornerstone for the burgeoning field of semiconductor spintronics. It is typically assumed to manifest as a momentum-dependent splitting of a single initially spin-degenerate band into two branches with opposite spin polarization. Combining(More)
