Wonil Nam, Yuming Zhao, Junyeob Song, Seied Ali Safiabadi Tali, Seju Kang, Wenqi Zhu, Henri Lezec, Amit Agrawal, Peter J. Vikesland, Wei Zhou
Ultrasensitive surface-enhanced Raman spectroscopy (SERS) still faces difficulties in quantitative analysis because of its susceptibility to local optical field variations at plasmonic hotspots in metallo-dielectric nanostructures. Current SERS calibration

Scalable microresonators for room-temperature detection of electron spin resonance from dilute, sub-nanoliter volume solids

October 28, 2020
Author(s)

Nandita S. Abhyankar, Amit K. Agrawal, Pragya R. Shrestha, Russell A. Maier, Robert D. McMichael, Jason P. Campbell, Veronika A. Szalai

Microresonators used for spin detection in volume-limited samples suffer from poor quality factors, which adversely affect sensitivity and ease of coupling to the microwave source. Here we adapt a metamaterial design with toroidal moment to confine
