Early Pancreatic Cancer Diagnosis via Ultrasensitive THz Toroidal Metasensing
Advanced Photonics Research, EarlyView.This study introduces a revolutionary terahertz metasurface biosensor using gold nanoparticles to boost sensitivity. It achieves precise detection of ultra‐low biomarker concentrations (1–1000 pg mL−1) with a 97.6 GHz/RIU sensitivity through optimized antibody binding.

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.

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.
