Noise Bounds in Multicarrier mmWave Doppler Measurements
More and more research groups are working on experimental research of millimeter wave (mmWave) wireless communications. Up to now, most mmWave measurements have been carried out in static scenarios. However, as the Doppler effect scales linearly with the carrier frequency, mmWave multicarrier transmission is prone to intercarrier interference caused by Doppler shifts. Today, mmWave radio freque...
متن کاملSolar Coronal Plasma in Doppler Measurements
Doppler tracking of an interplanetary spacecraft near solar conjunction is strongly affected by the plasma in the solar corona, the main competitive contribution in measurements of the gravitational deflection of light rays. With the simultaneous availability of carriers in X band and Ka band for interplanetary communications, the plasma contribution to the corona can be accurately eliminated a...
متن کاملSeebeck coefficient measurements of lithium isotopes
Lithium, owing to its many advantages, is of immense interest to the fusion community for its use as plasma facing component (PFC) material. Various experiments are under progress in the Center for Plasma Material Interactions (CPMI) at the University of Illinois at Urbana Champaign (UIUC) aimed at understanding the plasma–lithium interactions. In one such experiment called Solid/Liquid Lithium...
متن کاملReproducibility of carotid artery Doppler frequency measurements.
Doppler sonography of 29 extracranial carotid arteries was performed twice within three days or less. Angiography revealed stenoses with from 10 to 95% diameter reduction in 25 internal carotid arteries whereas four vessels were found to be normal. The systolic peak frequency of the internal carotid artery read from the Doppler spectrum (n = 29) could be reproduced very well. This was shown by ...
متن کاملPrecision Doppler measurements with steep dispersion.
Controlling the group velocity of light is a valuable resource for quantum and classical optical processing and high performance sensor technologies. In this context, slow-light (SL) and the associated steep dispersion have been proposed to increase the sensitivity of certain types of interferometers. Here, we show that the interaction of two intensity-balanced light beams in a SL medium can be...
