Accurate spin-dependent electron liquid correlation energies for local spin density calculations: a critical analysis
TL;DR: The authors assess various approximate forms for the correlation energy per particle of the spin-polarized homogeneous electron gas that have frequently been used in applications of the local spin density a...

Police radar detectors for detecting radar signals and determining the directional origin of the signal source
TL;DR: In this article, a police radar detector includes at least two antennas and preferably three or more antennas with detector circuitry shared among the antennas in a single detector housing, and the signals are detected in all antennas with the signal strengths in the different antennas being compared to determine the direction of origin of the signals.

Motor vehicle radar detector including amplitude detection
TL;DR: In this article, a radar detector for use in a motor vehicle employs amplitude detection to sense the presence of radar signals commonly used to monitor the speed of such motor vehicles, where amplitude signals are generated by down-converting received signals using a series of mixers, one of which is swept to insure signal detection, and compared to a threshold which is controlled such that noise is detected by the comparison on average a selected period of time.

Double-ridge waveguide to microstrip coupling
TL;DR: In this article, a double-ridge waveguide is coupled to a microstrip circuit by expanding the lower ridge of the waveguide by gradually increasing its width, and the upper ridge is gradually tapered over the length of the coupling and then sharply tapered adjacent the microstrip end.

The Fermi contact contribution to the Knight shift in Be from self-consistent spin-polarized calculations
TL;DR: In this paper, the Fermi contact contribution to the Knight shift is proportional to the sum of three spin densities (evaluated at the nucleus) arising from (i) the valence electrons at the Fermani surface, (ii) the core electrons, and (iii) the below the fermi surface.
