"called inverse square root law, shifts resonance from high-loss localized surface plasmon resonances to low-loss surface plasmon polaritons, resulting in 2-order-magnitude greater metal arrays' resonance quality... stronger nanoscale light-matter interactions... more powerful, efficient nanoscale optics: sensing, imaging, solar energy"
