An Inverted Honeycomb Plasmonic Lattice as an Efficient Refractive Index Sensor [PDF]
Nanomaterials, 2021 We present an efficient refractive index sensor consisting of a heterostructure that contains an Au inverted honeycomb lattice as a main sensing element. Our design aims at maximizing the out-of-plane near-field distributions of the collective modes of the lattice mapping the sensor surroundings.
