Exceptionally high Verdet constant in gold nanodisc arrays
Gajendra Mulay, Shraddha Choudhary, Ashwin A Tulapurkar +4
Magneto-optical effects in non-magnetic noble metals can be greatly enhanced by leveraging the in-plane Lorentz force at engineered plasmonic resonances. We demonstrate a 2D array…

Plasmonic quasicrystals for designable ultra broadband transmission enhancement and second harmonic generation
Sachin Kasture, Ajith P R, V J Yallapragada +4
Quasi-crystals are intriguing as they exhibit rotational symmetry and long range ordering but lack translational symmetry. 2-dimensional metal-dielectric patterns are interesting t…

Superluminal propagation and broadband omnidirectional antireflection in optical reflectionless potentials
L. V. Thekkekara, Achanta Venu Gopal, Sachin Kasture +2
Reflectionless potentials (RPs) represent a class of potentials that offer total transmission in the context of one dimensional scattering. Optical realization of RPs in stratified…
