Field confinement and its analysis in the THz range
Résumé
Confining the electromagnetic field in sub wavelength volume is a widespread challenge in any range of photonics. One of the specificities of the THz range is the relatively low losses of metal allowing the use of metallic structure to achieve this confinement. In this conference, we will show: - how such metallic structure allowed us to perform broadband spectroscopy on nanoliter-sized samples; - narrower band spectrometry on a fraction of nanolitres; and - characterize the near field of the photonic mode in our resonators
