Experimental exploration of longitudinal modes in spherical shells at 220 GHz – 330 GHz: applications to corneal sensing
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Restricted access - publisher's policySubmillimeter-wave and THz sensing of cornea leverage the layered tissue structure for assessments of corneal water content and thickness. The cornea is bounded by air on the anterior and an optically thick body of water ... -
Efficient analysis of sheets with nonzero thickness
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference lecture
Open AccessThe conventional scattering analysis of perfectly conducting plates neglects the scattering contribution of the rim in the discretization of the Electric-Field Integral Equation. This so-called thin-plate scheme manages ... -
X-parameters based characterization of PIN diodes for reconfigurable antenna assessment
(Íñigo Cuiñas Gómez, 2021)
Conference report
Restricted access - publisher's policyThis contribution presents the non-linear characterization up to 50 GHz of a PIN diode commonly used as switch for reconfigurable devices at microwave applications. Non-linear models are extracted by means of X-parameter ... -
Efficient analysis of thick curved metal sheets
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThe scattering analysis of perfectly conducting plates with the method-of-moment discretization of the Electric-Field Integral Equation has been traditionally carried out according to the thin-sheet approximation, which ... -
Fourier analysis of submillimeter-wave scattering from the human cornea
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessWave scattering from a human cornea illuminated with a submillimeter-wave Gaussian beam is explored with Fourier analysis. This new approach enabled us to investigate the cornea as a coated sphere rather than a homogenized ... -
