Claim 0:
1. 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.
