Improving sensitivity of existing surface plasmon resonance systems with grating-coupled short-range surface plasmons

Here we show that surface plasmon resonance sensors that typically use 760   nm wavelength Kretschmann – Raether coupling to a 50   nm thick gold film can have 3 times higher surface sensitivity by using local resonances from periodically arranged short-range modes in the same ...
