ABSTRACT:
Apparatus for measuring a characteristic of a body of material having first and second substantially parallel coaxial lines with distal extremities in relatively close proximity to each other and adpapted to be disposed in close proximity to the body of material. A transmitter is coupled to the first coaxial line for introducing electrical energy in the high frequency to a microwave range into the first coaxial line to cause an electromagnetic field to be established at the distal extremity of the first coaxial line and to extend into the body of material. A receiver is coupled to the second coaxial line for detecting any of the electromagnetic field coupled into it from the first coaxial line. A measurement device is coupled to the receiver means for ascertaining when any change occurs in the coupling of the electromagnetic field from the first coaxial line to the second coaxial line to determine said characteristic of the body of material.
