An additive manufactured K-Band Waveguide Coupler and K-Band Antennas in SLM-Technology

2020 23rd International Microwave and Radar Conference (MIKON), 2020
3D printing offers a very innovative opportunity for creating cheap or special rf-components like waveguides, couplers or antennas. However, these components require electrical conductive materials to be built of. Therefore, selective laser melting of metal powder is also an attractive production technology.

The K-Band Luminosity Function of Galaxies

Symposium - International Astronomical Union, 1997
The luminosity function of galaxies is central to many problems in cosmology, including the interpretation of faint number counts. The near-infrared provides several advantages over the optical for statistical studies of galaxies, including smooth and well-understood K-corrections and expected luminosity evolution. The K–band is dominated by near-solar

K-band diamond MESFETs for RFIC technology

2009 IEEE Radio Frequency Integrated Circuits Symposium, 2009
Diamond is one of the suitable semi-conductor for vacuum electronics replacement in high power and high frequency applications. Sub-micron gate-length (200 nm) Metal Semiconductor Field Effect Transistor (MESFETs) have been fabricated on h-terminated polycrystalline diamond and characterized in order to investigate the possibility of RFICs integration.

High-K band structures in 164Er

Zeitschrift für Physik A Hadrons and Nuclei, 1997
Several of the known rotational bands in 164Er are extended considerably (to around 35 h). In addition, a new coupled band is established and found to decay by an isomeric transition with t1/2 ≥ 170 nsec, to the 11t - state of the known Kπ =7− two-quasi-proton band. The new band is interpreted as a four-quasi-particle structure, with measured values of

The K-Band Luminosity Function

Symposium - International Astronomical Union, 1996
Investigations of broad band energy distributions of specific classes of sources requires homogeneous samples of a sufficiently large number of objects. Deep and homogeneous surveys in those energy ranges which are accessible to satellites only are rare. One such a field in the north ecliptic pole (NEP).

K’-band observations of the Evil Eye Galaxy and the implied K’-band dust albedo

1996
We are reporting the result of a new analysis of the observations of reddening and attenuation produced by the remarkable dust feature in the galaxy NGC 4826 (Evil Eye Galaxy), published by Witt et al. (1994). This analysis is based on multiple-scattering radiative transfer models for a disk galaxy with an overlying dust lane, and it includes the ...
