Breakdown and Discharge Characteristics of High Repetition Frequency Nanosecond Pulsed Air Dielectric Barrier Discharge

open access: yesHigh Voltage, EarlyView.
ABSTRACT This study explores the breakdown characteristics and discharge modes in a parallel plate air dielectric barrier discharge system using repetitive nanosecond pulses, with pulse repetition frequencies (PRFs) from 0.1 to 100 kHz. It examines how pulse parameters—PRF, pulse number and gas pressure—affect the memory effect, leveraging current and ...

Wireless Resonators With Coupled Versus Decoupled Units: Which Enhances Local SNR of RF Receive Arrays Better?

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2442-2450, April 2026.
ABSTRACT Purpose To compare two identically sized wireless resonator designs, one with strongly coupled units and the other with decoupled units, for their ability to enhance receive performance in MRI when used with local receive arrays. Methods Both wireless resonator designs were fabricated and experimentally evaluated for detuning efficiency, SNR ...

Ticept: Wideband Electrical Properties Tomography by Tissue Composition Assessment With Quantitative  1$$ {}^1 $$H 23$$ {}^{23} $$Na 39$$ {}^{39} $$K Multinuclear MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 3, Page 1503-1512, March 2026.
ABSTRACT Purpose To develop a noninvasive method for estimating dielectric properties over a wide frequency range from 50 to 600 MHz. Existing methods are limited in accuracy and provide single‐frequency results. Furthermore, accurate knowledge of dielectric properties becomes more important, since medical device design and safety evaluation ...
