Compact defected ground structure in microstrip technology

Electronics Letters, 2005
A meander microstrip line with defected ground structure is proposed. Its radiation loss and slow-wave effect are evaluated. The compact configuration presents broad stopband and improved slow-wave characteristics. A good agreement between simulation and measurement verifies the designed circuit.

Optical‐controlled magnon transport based on spin crossover switched molecular magnets

Smart Molecules, EarlyView.
A cyanide‐bridged W(V)–Fe(II) spin‐crossover single crystal was integrated into a magnon transport device, enabling reversible optical control of magnon transport through photo‐switched spin states. Abstract Molecule‐based devices that combine the advantages of fast time response and extremely low manipulation/transmission energy consumption of light ...

Using U‐Nets to Predict the Effects of Head Motion on Simulated Specific Absorption Rate for Ultra‐High Field Magnetic Resonance Imaging With Parallel Transmission

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 650-665, August 2026.
ABSTRACT Purpose Ultrahigh‐field MRI requires careful management of the specific absorption rate (SAR), which is subject and subject‐position dependent. Within‐scan subject motion may exacerbate local SAR exposure, necessitating large safety margins to prevent SAR underestimation, which hampers imaging performance.

Features of the microstrip proportional counter technology (invited) [PDF]

Review of Scientific Instruments, 1992
The microstrip proportional counter (MSPC) is a new approach in gas-filled detector technology. In contrast with the classical multiwire proportional counter (MWPC) detectors, the electrodes of the MSPC are deposited by photolithographic techniques onto a rigid substrate. The technique offers many important advantages: An optimal energy resolution; The

Time‐Domain Simulator for Nonuniform Transmission Lines: An Educational Tool

Computer Applications in Engineering Education, Volume 34, Issue 4, July 2026.
ABSTRACT The study of transmission lines is a key topic in electrical and electronic engineering education. However, their theoretical formulation can be complex, often hindering students' understanding of the underlying physical phenomena. In contrast, transmission lines exhibit intuitive and engaging behaviors. To address this challenge, we developed
