State-of-the-art high resolution active remote sensing imaging radar, TerraSAR-X, is having all-weather and all-time data acquisition capability. It is a promising tool for mapping snow and glaciers in mountainous region. The current study has been done using dual polarization (HH/VV) Synthetic Aperture Radar (SAR) data of TerraSAR-X (TSX), to estimate the snow physical properties (snow cover, ...

Structural inversion asymmetry controls the magnitude of Rashba spin-orbit coupling in the electron energy spectrum of a narrow band gap semiconductor. We investigate this effect for a series of two-dimensional electron gases in In0.52Ga0.48As quantum wells, surrounded by In0.52Al0.48As barriers, where either one or two electric subbands are populated. Structural inversion asymmetry does not ex...

We develop fast discrete Fourier transforms (and their adjoints) from a square in space to a disk in the Fourier domain. Since our new transforms are not unitary, we develop a fast inversion algorithm and derive corresponding estimates that allow us to avoid iterative methods typically used for inversion. We consider the eigenfunctions of the corresponding band-limiting and space-limiting opera...

On the basis of the Gaussian vertical backscatter (GVB) model, this paper proposes a new method for extracting pine forest height and forest underlying digital elevation model (FUDEM) from multi-baseline (MB) P-band polarimetric-interferometric radar (PolInSAR) data. Considering the linear ground-to-volume relationship, the GVB is linked to the interferometric coherences of different polarizati...

We propose an on-demand single-photon source for quantum cryptography using a metal–insulator–semiconductor quantum dot capacitor structure. The main component in the semiconductor is a p-doped quantum well, and the cylindrical gate under consideration is only nanometres in diameter. As in conventional metal–insulator–semiconductor capacitors, our system can also be biased into the inversion re...

Using two-frequency driving in two dimensions opens up new possibilities for Floquet engineering, which range from controlling specific symmetries to tuning the properties of resonant gaps. In this work, we study two-band lattice models subject two-tone and analyze resulting effective band structures both numerically analytically. On one hand, extend methodology Sandholzer et al. [Phys. Rev. Re...
