Universal radiation dynamics by temporal transitions in optical waveguides
Amir Shlivinski, Yakir Hadad
When an excited electromagnetically open optical waveguide goes through a temporal transition of its material properties, it radiates to the ambient surroundings. In this letter, w…

Optimal Design of Dallenbach Absorbers Under Broadband Broad-Angle Illumination
Chen Firestein, Amir Shlivinski, Yakir Hadad
The classical scenario where a \emph{single plane-wave} field impinge a Dallenbach absorber is well studied both theoretically and experimentally. However, occasionally a \emph{spe…
