Through-the-Wall Image Reconstruction via Reweighted Total Variation and Prior Information in Radio Tomographic Imaging

open access: yesIEEE Access, 2020
This paper focuses on the application of radio tomographic imaging in through-the-wall image reconstruction. By using the simple wireless communication devices, e.g., Wi-Fi cards, the whole building layout can be reconstructed with only the received ...

Correlations in interfering electrons irradiated by nonclassical microwaves [PDF]

open access: yesPhysical Review A 66, 033813 (2002), 2003
Electron interference in mesoscopic devices irradiated by external non-classical microwaves, is considered. In the case of one-mode microwaves, it is shown that both the average intensity and the spectral density of the interfering electrons are sensitive to the quantum noise of the microwaves.

Microwaves Are Everywhere: “SMM: Nano-Microwaves” [PDF]

open access: yesIEEE Journal of Microwaves, 2021
If the Twentieth Century boasted of the Space Age and the Computer Age, the Twenty-First Century is certainly starting off with the Age of Biology, or at least Biochemistry. The enormous impact of CRISPR (clustered regularly interspaced short palindromic repeats), LAMP (loop-mediated isothermal amplification), cryo-EM (electron microscopy), and many ...

Remotely sensed transport in microwave photoexcited GaAs/AlGaAs two-dimensional electron system [PDF]

open access: yesAppl. Phys. Lett. 102, 242113 (2013), 2013
We demonstrate a strong correlation between the magnetoresistive and the concurrent microwave reflection from the microwave photo-excited GaAs/AlGaAs two-dimensional electron system (2DES). These correlations are followed as a function of the microwave power, the microwave frequency, and the applied current.

RIPless Based Radar Waveform Analysis in Sparse Microwave Imaging

open access: yesLeida xuebao, 2013
The echo data can be modeled as the product of the Toeplitz matrix and reflectivity of the observed scene. The row of the Toeplitz matrix is the time-shift of the transmitted signal.

Design of Compact Quasi-Elliptic Bandpass Filters Based on Coaxial Inset Resonators

open access: yesIEEE Access, 2023
This article reports a novel inset resonator configuration for coaxial filter applications with quasi-elliptic responses. The design and analysis of the inset resonator are discussed in detail and accurately modeled as a capacitively-loaded stepped ...

CMORPH: A Method that Produces Global Precipitation Estimates from Passive Microwave and Infrared Data at High Spatial and Temporal Resolution

open access: yes, 2004
A new technique is presented in which half-hourly global precipitation estimates derived from passive microwave satellite scans are propagated by motion vectors derived from geostationary satellite infrared data.
