The infrared and Raman spectra of bicyclo[1.1.1]pentane and of its 1-d1 and 1,3-d2 isotopomers were determined, and the intensities of the infrared bands w... KB Wiberg,RE Rosenberg,ST Waddell - 《J.phys.chem》 被引量: 313发表: 1992年 Microwave Spectrum, Structure, and Dipole Moment...
Microwave spectrum, structure, dipole moment, and barrier to internal rotation of phosphine-borane The microwave spectra in the P, K, and R bands of 16 isotopic species of phosphine-borane (H3PBH3) have been measured and the following structural paramete... JR Durig,YS Li,IA Carreira,......
Huawei's enterprise microwave solutions include microwave transmission and radar sensing, the first of which is based on Huawei's leading 5G wireless technologies. Microwave transmission solutions consist of products working at unlicensed spectrum (sub-6 GHz), common frequency bands (6–38 GHz), and...
Long-haul microwave plays a pivotal role in fiber-lacking areas. To meet the demand for over 20 Gbit/s capacity in these places, multi-band and multi-carrier aggregation is required to work around the insufficiency of spectrum. It is also necessary to address the tower loads and tower rents...
Owing to the scarcity of spectrum resources in the 6–11 GHz band, microwave solutions nowadays must combine multiple channels or frequency bands in order to achieve ultra-large bandwidth. Until now, L6/U6 GHz, 7/8 GHz, and 11 GHz bands required the installation of different antennas. This ...
The cw dye laser excitation spectrum of the (110)-(000) and (021)-(000) vibronic bands of the A1A″-X1A′ system of DNO was observed between 16530 and 1686... J.C.,Petersen - 《Journal of Molecular Spectroscopy》 被引量: 30发表: 1985年 The electronic spectrum of the previously unk...
(i.e., setting the VOA to zero transmission). We sweep the frequency of an RF tone at the input to the intensity modulator and measure the output RF power at the same frequency using a synchronized RF spectrum analyzer. The device produces a bandpass response, revealing multiple acoustic ...
The jet-cooled Fourier-transform microwave spectrum of N-methylaniline (C 6H 5-NHCH 3) was recorded in the region of 10–26 GHz, and was analyzed to determine rotational constants and nuclear quadrupole coupling constants. Furthermore, a Coriolis-like coupling parameter characterizing an interaction...
Development of Novel and High Gain Microstrip Patch Antennas at Different Frequency Bands for 6G Applications Wireless communications need antennas of different sizes, shapes, frequency-bands, bandwidths, and radiation patterns due to technical requirements, physic...
