Thermal infrared plasmonics [PDF]

open access: yes2011 XXXth URSI General Assembly and Scientific Symposium, 2011
We examine a new class of infrared (IR) plasmonic devices that convert thermal radiation into bound surface plasmon polaritons (SPP's). The coupling of these SPP's into nanometer scale metal insulator metal (MIM) channels is investigated both theoretically and experimentally.
