Optical nanoswitch: an engineered plasmonic nanoparticle with extreme parameters and giant anisotropy
TL;DR: In this article, an engineered resonant nanoparticle composed of two conjoined hemispheres, whose optical response may be changed at will from an ideal electric conductor to an ideal magnetic conductor, is presented.

Acoustic meta-atom with maximum Willis coupling
TL;DR: In this article, a meta-atom with Willis coupling is proposed, which is much simpler and less prone to thermo-viscous losses than previously reported structures, and the authors perform two-dimensional experiments to measure the strong Willis coupling, supported by numerical calculations.

TL;DR: In this article, the authors proposed a general procedure that allows designing Yagi-Uda antennas with low scattering profile, which is able to operate efficiently within a given frequency band, while being electromagnetically undetectable in another desired frequency range.
Limitations of Sensing at an Exceptional Point
TL;DR: In this paper , the authors study the fundamentals of sensing in linear scattering systems operating near an exceptional point (EP) and analyze the specific role of EPs and associated amplification mechanisms, and show that eigenvalue variations under perturbation are not a good measure of the overall sensor performance near an EP.

Embedded scattering eigenstates using resonant metasurfaces
Alex Krasnok,Andrea Alù +1 more
TL;DR: In this article, the authors explore the realization of these bound states in the continuum using ultrathin metasurfaces composed of arrays of nanoparticles, and explore the use of Ag nanoparticles coated with gain media shells to compensate material loss and revive the EE despite realistic loss in plasmonic materials.
