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 ... -
An UWB Tapered Slot Vivaldi Antenna (TSA) with improved characterestics
