Science, 1984
Observations of Uranus at wavelengths of 2 and 6 centimeters with the Very Large Array were made in 1980 and 1981. The resulting maps of brightness temperature show a subsolar symmetry at 2 centimeters but a near-polar symmetry at 6 centimeters. The 6-centimeter maps show an increase in temperature from equator to pole with some evidence for a warm ...

Measurement Techniques, 2000
Designs and basic characteristics are considered for imagers having ellipsoidal-mirror and lens antennas. These operate in the 8 mm range and are intended for ultrasensitive measurement of millimeter-range field patterns and for the construction of images by computer processing.

Compressive-processing microwave imaging
2017 Sixth Asia-Pacific Conference on Antennas and Propagation (APCAP), 2017Microwave imaging techniques have been widely developed in the last years, exploiting different inversion strategies in several applicative scenarios. Among these, Compressive Sensing (CS) has been recently introduced in the electromagnetic community as an efficient and effective tool for solving inverse scattering problems. Anyway, despite the sensing

Imaging Techniques for Microwave Diagnostics
Contributions to Plasma Physics, 2011AbstractImaging diagnostics, such as Electron Cyclotron Emission Imaging (ECEI) and Microwave Imaging Reflectometry (MIR), exhibit unique characteristics that make them particularly well suited to the validation of theoretical models for plasma instabilities and turbulent fluctuations.

Reference phantoms for microwave imaging
2017 11th European Conference on Antennas and Propagation (EUCAP), 2017Microwave imaging offers an alternative modality for breast cancer screening and for the diagnosis of cerebrovascular accidents. Before clinical application, the performances of microwave imaging systems have to be assessed on anatomically detailed anthropomorphic phantoms.

Applied Physics A, 2013
By using an on-chip microwave sensor employing spintronic and spin caloritronic principles, a spintronic technique has been developed for microwave imaging. This novel technique allows microwave fields to be directly rectified on chip into dc voltage signals. This imaging technique does not require complicated and expensive microwave systems to operate,

Machine Learning For Microwave Imaging
2020 14th European Conference on Antennas and Propagation (EuCAP), 2020This paper proposes a fully-connected artificial neural network (ANN) approach for addressing the full-wave inverse scattering problem in a quantitative fashion. The proposed scheme processes the scattered field samples collected at receivers locations and provides as output an estimate of the unknown complex permittivity in strongly non-linear ...
