Abstract

A spaced-plate waveguide probe for dielectric measurement of a material under test is disclosed. The probe has a first plate and a second plate spaced from the first plate. There is a first strip of a first dielectric material extending between the first plate and the second plate at first side of the first plate and the second plate. A second strip of a second dielectric material extends between the first plate and the second plate at a second side of the first plate and the second plate. A third strip of a third dielectric material extends between the first plate and the second plate between the first strip and the second strip.
