Terahertz time domain spectroscopy of a single split ring resonator coupled to an amino acid crystal
Résumé
Split Ring Resonators (SRRs) have been used in large arrays to interact with objects much smaller than the wavelength in the terahertz range. Using arrays of SRRs facilitates the measurements, but prevents one from extracting accurate information regarding the object properties in this frequency range. Here, we demonstrate that the experiment is possible with a single SRR. We measured the transmission spectrum of a single SRR coupled with less than 1µm of glutamic acid (GA) crystals, and extracted information on the 1.2THz vibration mode of GA crystals.
