Cavity Resonators

Volumetric and non-invasive measurements of plant biomass are an important target to assist plant growth analysis and to derive information and proxies about plant water status. At IBG-2 we have developed prototypes that use the cavity resonance physics principle applied to this problem. In the last few years we have explored a range of electromagnetic frequencies and cavity geometries for measuring whole shoot water content, ranging from benchtop and laboratory instruments to a large cavity in use for large plants and that are also included as a possible measurement mode in the phenotyping platform SCREEN House.
