The power of VNA-driven quasi-optics to sense group molecular action in condensed phase systems

Abstract

The versatility for quasi-optical circuits, driven by modern vector network analysers, is demonstrated for the purpose of low energy (meV) coherent spectroscopy. One such example is shown applied to the curing dynamics of a non-mercury-based dental cement. This highlights the special place the methodology holds as a 'soft-probe' to reveal the time-resolved energetics of condensed phased systems as they self-organise to adopt their low energy state.
