System for measuring a microwave dielectric property of a solid material under force

A system for measuring a microwave dielectric property of a solid material under force, comprising:

• a microwave dielectric tester comprising an open coaxial resonator;
• a pressure loading device;
• a shield case for microwave electromagnetic shielding;
• a spring seat;
• and
• a computer;
• wherein the microwave dielectric tester is connected to the spring seat;
• the pressure loading device is connected to the computer;
• the microwave dielectric tester and the pressure loading device are arranged inside the shield case, a sample is in contact with an upper portion of the microwave dielectric tester;
• the pressure loading device is configured to load a horizontal pressure on the sample of the solid material;
• the microwave dielectric tester is configured to measure a dielectric constant and a dielectric loss of the sample under the horizontal pressure, and send measured dielectric constant and dielectric loss to the computer;
• the computer is configured to select a testing mode based on a test demand;
• the shield case is configured to shield an electromagnetic interference from an external environment;
• and the spring seat comprises an embedded spring that is attached to a bottom of the microwave dielectric tester, and the spring seat is configured to buffer the microwave dielectric tester against a compression caused by a deformation of the sample.
