Extreme Optical Field Confinement and Enhancement in a Plasmonic Picopatch within a Nanoparticle-on-Mirror Resonator
Jinna He, Mario Zapata-Herrera, Xabier Arrieta +4
Plasmonic resonances in metallic nanogaps can confine light into nanometric regions, but reaching modes of volume nm remains challenging. We present a detailed theo…
Chiro-Optical Structures with Magnetizable Plasmonic Elements for Modulating the Chiral Transmission of Light
Kaysiyavash Kaykavoosi, Nicklas Anttu, Mario Zapata-Herrera +3
Manipulating external stimuli is crucial for enhancing and controlling the optical response in chiral structures. This study introduces chiral structures composed of single, dimer,…
Size change effect on the optical behavior of ultra small metal particles
Mario Zapata-Herrera, Angela S. Camacho
In this paper we analyse the importance of a detailed description of the electronic transitions in ultra-small nanoparticles through the optical response to very small changes of s…
Near field enhancement due to the optical response of small nanoparticles
Mario Zapata-Herrera, Jefferson Flórez, Angela Camacho +1
In this work we study the strong confinement effects on the electromagnetic response of metallic nanoparticles. We calculate the field enhancement factor for nanospheres of various…
