Plasmon localization and giant fields in holographic metasurface for SERS sensors
Andrey K. Sarychev, Andrey Ivanov, Andrey N. Lagarkov +9
We present SERS-active metal holographic metasurfaces fabricated from metal periodical nanograting deposited on a dielectric substrate. The metasurface consists of a modulated diel…

Limit possible electric field in plasmon nanogap resonator
Andrey K. Sarychev, Andrey V. Ivanov, Grégory Barbillon
We propose the theory of the plasmon excited in ultra-narrow plasmonic gap formed by a metal cylinder on a metal surface, that generates a huge resonant local electromagnetic field…
