(2018-12-18)
Article
Open AccessCharles Darwin, en su libro "El Origen de las Especies", sentenció: No es el animal más fuerte, ni el más inteligente, el que sobrevive, sino aquel que es capaz de adaptarse a los canvios del entorno. Propiciado por ... -
Collimated beam FMCW radar for vital sign patient monitoring
(2018-12-18)
Article
Open AccessPatient monitoring of vital signals such as breathing rhythm and heart beat rate can be done remotely by the use of a radar system. This approach is advantageous since it does not require any contact with the patient. ... -
Versatile and accurate schemes of discretization for the electromagnetic scattering analysis of arbitrarily shaped piecewise homogeneous objects
(2018-12-01)
Article
Restricted access - publisher's policyThe discretization by the method of moments (MoM) of integral equations in the electromagnetic scattering analysis most often relies on divergence-conforming basis functions, such as the Rao–Wilton–Glisson (RWG) set, which ... -
A microwave invisibility cloak: the design, simulation, and measurement of a simple and effective frequency-selective surface-based mantle cloak
(2018-06-26)
Article
Open AccessIn recent years, there has been a growing interest in developing invisibility cloaks that can conceal an object. These techniques are often based either on coating a dielectric or conducting object with a homogeneous ... -
Comparative efficiency and power assessment of optical photoconductive material-based terahertz sources for wireless communication systems
(2019-01-01)
Article
Open AccessTerahertz band has recently attracted the attention of the communication society due to its huge bandwidth and very high-speed wireless communications capability. It has been utilized in a variety of disciplines including ... -
A compact dual-band planar monopole antenna using fractal rings and A Y-shaped feeding transmission line
(De Gruytr, 2018-01-01)
Article
Restricted access - publisher's policyThis paper presents a novel design approach of a compact dual-band monopole antenna with an overall size of 18.9x13x1.6mm3. The proposed antenna is composed of a fractal ring shaped patch fed by a Y-shaped transmission ... -
Assessment of 3-D printing technologies for millimeter-wave reflectors
(Institute of Electrical and Electronics Engineers (IEEE), 2018-07-20)
Article
Open AccessThree different 3D printing technologies: Stereolithography (SLA), Fused Deposition Modeling (FDM) and HP Multi Jet Fusion Technology (MJF) are compared to build a parabolic reflector operating at 100 GHz. Fabrication ... -
Dielectric properties of colon polyps, cancer, and normal mucosa: Ex vivo measurements from 0.5 to 20 GHz
(2018-06-15)
Article
Open AccessColorectal cancer is highly preventable by detecting and removing polyps, which are the precursors. 20 Currently, the most accurate test is colonoscopy, but still misses 22% of polyps due to visualization limitations. In ... -

Open AccessA reconfigurable antenna (RA) capable of steering its beam into the hemisphere corresponding to ¿ ¿ {-40°,0°,40°}, Ø ¿ {0°,45°,90°,-45°}, and of changing 3-dB beamwidth, where ¿3dB ¿ (40°,100°), Ø ¿ {45°,90°,-45°} for ... -
Assessment of LTCC-based dielectric flat lens antennas and switched-beam arrays for future 5G millimeter-wave communication systems
(2017-10-30)
Article
Open AccessIEEE This paper presents design, LTCC fabrication, and full experimental verification of novel dielectric flat lens antennas for future high data rate 5G wireless communication systems in the 60 GHz band. We introduce and ... -
Annual traffic noise levels estimation based on temporal stratification
(2017-10-19)
Article
Restricted access - publisher's policyThis paper proposes a temporal sampling strategy that increases the accuracy of long-term noise level estimation and allows to establish the estimation error according to the number of sampled days. Days of the week are ... -
Versatile and accurate schemes of discretization in the scattering analysis of 2-D composite objects with penetrable or perfectly conducting regions
(2017-05-01)
Article
Open AccessThe method-of-moment discretization of boundary integral equations in the scattering analysis of closed infinitely long (2-D) objects, perfectly conducting (PEC) or penetrable, is traditionally carried out with continuous ...
