Plane-wave scattering by self-complementary metasurfaces in terms of electromagnetic duality and Babinet's principle [PDF]

, 2013
We investigate theoretically electromagnetic plane-wave scattering by self-complementary metasurfaces. By using Babinet's principle extended to metasurfaces with resistive elements, we show that the frequency-independent transmission and reflection are ...

Renal Resistive Index: Response to Shock and its Determinants in Critically Ill Patients

Shock, 2019
Introduction: Shock is characterized by micro- and macrovascular flow impairment contributing to acute kidney injury (AKI). Routine monitoring of the circulation regards the macrocirculation but not the renal circulation which can be assessed with ...
