Exceptional Points in the Scattering Resonances of a Sphere Dimer
Emanuele Corsaro, Filippo Capolino, Carlo Forestiere
We investigate exceptional points of degeneracy (EPDs) in electromagnetic scattering of a sphere dimer from the electroquasistatic limit to the fully retarded regime. In the quasis…

Third Harmonic Generation in Transparent Longitudinal Epsilon-Near-Zero Multilayers
Wallace Jaffray, Sven Stengel, Domenico de Ceglia +5
Epsilon near zero (ENZ) materials can dramatically enhance local optical fields, enabling nonlinear interactions at relatively low intensities. Yet, near their plasma frequency, co…
