Correlation matrix methods to assess the stirring performance of electromagnetic reverberation chambers [PDF]

Wave Motion, 2019
Abstract The use of correlation matrices to evaluate the number of uncorrelated stirrer positions of electromagnetic reverberation chambers has widespread applications in electromagnetic compatibility. We present a review of recent methods based on multivariate correlation functions that relates statistical inhomogeneities in space (frequency) to the

Regionally resolved cardiac metabolism using a dipole‐loop array coil for 7 T 31P‐MRSI

Magnetic Resonance in Medicine, Volume 94, Issue 2, Page 480-496, August 2025.
Abstract Purpose We introduce a novel commercial phosphorus‐31 (31P) dipole‐loop array coil, describing the coil hardware and testing its performance on phantoms. We used this coil to assess cardiac metabolism per region in healthy volunteers. Methods B1+ field maps were simulated and compared to maps measured with a set of CSI sequences with varying ...

A shielded 32‐channel body transceiver array with integrated electronics for 7 T

Magnetic Resonance in Medicine, Volume 94, Issue 2, Page 852-866, August 2025.
Abstract Purpose Develop a 32‐channel transceiver array for 7 T body imaging that incorporates an RF shield, improves SNR, lowers g‐factors, and is robust to external loading. Methods The addition of a local RF shield was first investigated for single resonant blocks consisting of either one loop and a dipole (LD) or three loops and a dipole (3LD).

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide

Advanced Functional Materials, Volume 35, Issue 27, July 3, 2025.
An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Volumetric and Diffusion Tensor Imaging Abnormalities Are Associated With Behavioral Changes Post‐Concussion in a Youth Pig Model of Mild Traumatic Brain Injury

NMR in Biomedicine, Volume 38, Issue 7, July 2025.
We developed a translational, closed‐head, mild traumatic brain injury in adolescent pigs. DTI and volumetric analysis showed abnormalities in the integrity and volume of white and gray matter structures. Behavioral testing for memory and anxiety also indicated behavioral deficits after injury.

On Measurement of Reverberation Chamber Time Constant and Related Curve Fitting Techniques [PDF]

, 2015
The reverberation chamber time constant quantifies how fast a reverberation chamber loses its stored energy at different frequencies, which makes it a very important parameter in many power related tests, such as the measurement of antenna efficiency ...

Probability Distribution of the Quality Factor of a Mode-Stirred Reverberation Chamber

, 2012
We derive a probability distribution, confidence intervals and statistics of the quality (Q) factor of an arbitrarily shaped mode-stirred reverberation chamber, based on ensemble distributions of the idealized random cavity field with assumed perfect ...
