Assessment of 3-D printing technologies for millimeter-wave reflectors
(Institute of Electrical and Electronics Engineers (IEEE), 2018-07-20)
Article
Accés obertThree 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
Accés restringit per política de l'editorialColorectal 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 ... -
