Millimeter Wave Rotational Spectrum and Centrifugal Distortion
Intensive studies have been carried out on the rotational spectra of various isotopic species of ketene, H2C = C = 0 , since 1950 [ 1 6 ] . The centrifugal distortion analysis of ketene [3, 4 ] , together with information from additional infrared data [3, 5 ] , enabled Mallinson and Nemes [6] to reevaluate the molecular force field for ketene. Recently, microwave investigations on the higher ho...
متن کاملMillimeter-Wave Spectrum of the NO Dimer
The pure rotational spectrum of the NO dimer, (14N16O)2, has been studied in the 225-400 GHz millimeter-wave region by means of direct absorption in a supersonic jet expansion. Previously, only 4 rotational transitions of (NO)2 had been measured in the microwave region. To these, we have added 66 new millimeter-wave transitions with values of J ranging from 4 to 16 and of Ka from 2 to 7. Most t...
متن کاملPulse Modulation of Millimeter Wave Tubes
Various techniques for producing narrow pulse ( f 5 ns) modulation of millimeter wave tubes, such as extended interaction amplifiers, magnetrons, and traveling-wave tubes, are discussed. In order to achieve the narrow pulsewidth, the switch, pulse forming circuitry, as well as the tube interface, must satisfy very stringent requirements. In particular, the switch must operate at kilovolt (kV) l...
متن کاملBeamforming Based Full-Duplex for Millimeter-Wave Communication
In this paper, we study beamforming based full-duplex (FD) systems in millimeter-wave (mmWave) communications. A joint transmission and reception (Tx/Rx) beamforming problem is formulated to maximize the achievable rate by mitigating self-interference (SI). Since the optimal solution is difficult to find due to the non-convexity of the objective function, suboptimal schemes are proposed in this...
