Performance Comparison of Reflector- and Planar-Antenna Based Digital Beam-Forming SAR
The trend in the conception of future spaceborne radar remote sensing is clearly toward the use of digital beamforming techniques. These systems will comprise multiple digital channels, where the analog-to-digital converter is moved closer to the antenna.

Magnetization switching by microwaves initially rotating in opposite direction to precession
A common understanding of magnetization switching in microwave-assisted magnetization reversal is that the rotation direction of the microwaves should be the same with the precession direction of the magnetization.

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

Dual-Frequency Airborne SAR for Large Scale Mapping of Tidal Flats
Digital elevation models of tidal flats are a most valuable data source for the water management of coastal areas and need frequent updates to account for changes in sedimentation, erosion and identification of damages in building infrastructure.

Detection of Low RCS Unmanned Air Systems Using K-Band Continuous Wave Doppler Radar
UASs (Unmanned Air Systems) are universally used in many activities, spanning from leisure-commercial to military applications. Accordingly, as the number of UASs operating in the sky increases, so does the need to detect and identify them, in order to ...

Single Cooper pair tunneling induced by non-classical microwaves
A mesoscopic Josephson junction interacting with a mode of non-classical microwaves with frequency $\omega$ is considered. Squeezing of the electromagnetic field drastically affects the dynamics of Cooper tunneling.

Magnetization dynamics in the single-molecule magnet Fe8 under pulsed microwave irradiation [PDF]
We present measurements on the single molecule magnet Fe8 in the presence of pulsed microwave radiation at 118 GHz. The spin dynamics is studied via time resolved magnetization experiments using a Hall probe magnetometer.
