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 ...

AI-managed cognitive radio digitizers
(Institute of Electrical and Electronics Engineers, 2022)
Embedding Artificial Intelligence (AI) in integrated circuits is one of the technology pillars of the so-called digital transformation. Nowadays, the vast majority of electronic devices benefits from digital signal ...

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 ...
