Design and evaluation of an antenna applicator for a microwave colonoscopy system
(2019-08-01)
Article
Open AccessThis paper presents a design of a compact antenna applicator for a microwave colonoscopy system. Although colonoscopy is the most effective method for colorectal cancer detection, it suffers from important visualization ... -
A dynamic load balancing method for the evaluation of chemical reaction rates in parallel combustion simulations
(Elsevier, 2019-08-15)
Article
Restricted access - publisher's policyThe development and assessment of an efficient parallelization method for the evaluation of reaction rates in combustion simulations is presented. Combustion simulations where the finite-rate chemistry model is employed ... -
3-D printed UWB microwave bodyscope for biomedical measurements
(2019-02-15)
Article
Open AccessIn this letter, a three-dimensional (3-D) printed compact ultrawideband (UWB) extended gap ridge horn (EGRH) antenna designed to be used for biological measurements of the human body is described. The operational frequency ... -
La formación en ingeniería para la sociedad de la información.
(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
Open AccessThis 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 ... -
