Abstract
The present disclosure provides a measuring device, a measuring apparatus, and a measuring method for a dielectric constant of a liquid crystal. The measuring device includes: a first substrate and a second substrate disposed to be opposite to each other; a resonant structure layer disposed on a side of the first substrate facing the second substrate. a cavity for receiving the liquid crystal to be measured is defined between the first substrate and the second substrate. The above measuring device is applied to measurement of the dielectric constant of the liquid crystal in the terahertz wave band.
