Metasurfaces of Capacitively Loaded Metallic Rings for Magnetic Resonance Imaging Surface Coils
(Springer Nature, 2023)
his work investigates the use of a metasurface made up of a two-dimensional array of capacitively loaded metallic rings to enhance the signal-to-noise ratio of magnetic resonance imaging surface coils and to tailor the ...

Simplified single-phase clock scheme for MOBILE networks
(Institute of Electrical and Electronics Engineers, 2011)
MOBILE networks can be operated in a gate-level pipelined fashion allowing high through-output. If MOBILE gates are directly chained, a four-phase clock scheme is required for this. A single-phase scheme is possible adding ...

Dual capacitive-inductive nature of periodic graphene patches: Transmission characteristics at low-terahertz frequencies
(American Physical Society, 2013)
We report on the dual nature (capacitive and inductive) of the surface impedance of periodic graphene patches at low-terahertz frequencies. The transmission spectra of a graphene-dielectric stack shows that patterned ...

Design of Broadband Aperture-Coupled Stacked Microstrip Antennas Using Second-Order Filter Theory
(IEEE, 2022-07)
In this article, the authors propose a lumped circuit methodology for the design of broadband stacked microstrip patch antennas fed through an aperture. First, an equivalent circuit (EC) is introduced for the antenna. The ...

Reliability improvement of SRAM PUFs based on a detailed experimental study into the stochastic effects of aging
(ELSEVIER GMBH, 2024)
Physical Unclonable Functions (PUFs) have gained attention as a lightweight hardware security primitive. In particular, the SRAM-based PUF uses the unpredictable power-up value of the cells within an SRAM. Although these ...

Concentration-polarization electroosmosis for particle fractionation
(Royal Society of Chemistry, 2024-05-03)
Concentration-polarization electroosmosis (CPEO) refers to steady-state electroosmotic flows around charged dielectric micro-particles induced by low-frequency AC electric fields. Recently, these flows were shown to cause ...
