An antenna array utilizing slotted conductive slab: inspired by metasurface and defected ground plane techniques for flexible electronics and sensors operating in the millimeter-wave and terahertz spectrum
(Springer, 2023)
Artículo / Artikulua,
This paper describes an innovative design of an antenna array that is metamaterial inspired using sub-wavelength slots and defected ground structure (DGS) for operation over millimeter-wave and terahertz (THz) spectrum. ...
3D-ray launching MIMO channel geometric estimation
(IEEE, 2022)
Artículo / Artikulua,
The complete multiple-input–multiple-output
(MIMO) channel simulation in deterministic techniques can
be a computationally intensive task, due to the inherent scenario’s
complexity and number of antennas. The spatial ...
Novel concentric hexagonal-shaped RFID tag antenna with T-shaped stub matching
(IEEE, 2021)
info:eu-repo/semantics/article,
This paper presents a unique concentric hexagonal-shaped ring antenna for radio frequency identification (RFID) tags. The rings are excited with a common microstrip feedline. The radiation characteristics of the antenna ...
All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ...
Stripline multilayer devices based on Complementary Split Ring Resonators
(MDPI, 2022)
Artículo / Artikulua,
A new analytic design for multilayer stripline devices in planar circuit technology is presented. The Complementary Split Ring Resonator (CSRR) is used as a sub-wavelength resonant particle, which provides high-Q resonances ...
Optical-microwave sensor for real-time measurement of water contamination in oil derivatives
(Elsevier, 2023)

This paper presents a novel microwave sensor using optical activation for measuring in real-time the water
contamination in crude oil or its derivatives. The sensor is constructed from an end-coupled microstrip resonator
that ...
Metamaterial inspired electromagnetic bandgap filter for ultra-wide stopband screening devices of electromagnetic interference
(Springer, 2023)
Artículo / Artikulua,
Presented here is a reactively loaded microstrip transmission line that exhibit an ultra-wide
bandgap. The reactive loading is periodically distributed along the transmission line, which is
electromagnetically coupled. ...
Diffuse-scattering-informed geometric channel modeling for THz wireless communications systems
(IEEE, 2023)
Artículo / Artikulua,
Surpassing 100 Gbps data throughput is a key objective and an active area of research for sixth-generation (6G) wireless networks that can only be met by exploiting the TeraHertz (THz) frequency band (0.3 - 10 THz). THz ...
Metamaterials and their application in the performance enhancement of reconfigurable antennas: a review
(MDPI, 2023)
