Time-Domain Excitation of Finite-Lifetime Resonances and Their Exceptional Points
Asaf Farhi, Dror Hershkovitz, Andrea Alu +1
Resonances associated with complex-frequency poles are ubiquitous across physics and can arise in any open system, ranging from subwavelength particles and cavities to biological s…

Iris-assisted Terahertz Field-Induced Second Harmonic Generation in Air
Amit Beer, Dror Hershkovitz, Sharly Fleischer
Terahertz field-induced second harmonic generation (TFISH) is a technique for optical detection of broad-band THz fields. We show that by placing an iris at the interaction volume…
