In this paper we report on a detailed investigation of the quality Q factor exhibited by metal-nanostrip resonators with a bent axis. A detailed comparison of the Q with the quasistatic limit value demonstrates that under a large bending of the strip axis the resulting split-cylinder nanoresonators exhibit a Q that is exceeding the quasistatic Q in the near infrared. Also, a possible application of high-Q split-cylinder nanoresonators as high-sensitive plasmonic sensors is proposed.

Abstract
In this paper we report on a detailed investigation of the quality Q factor exhibited by metal-nanostrip resonators with a bent axis. A detailed comparison of the Q with the quasistatic limit value demonstrates that under a large bending of the strip axis the resulting split-cylinder nanoresonators exhibit a Q that is exceeding the quasistatic Q in the near infrared. Also, a possible application of high-Q split-cylinder nanoresonators as high-sensitive plasmonic sensors is proposed.File in questo prodotto:
