| Abstract: |
| Objective To study on the phase transition phenomenon of adaptive intelligent electromagnetic shielding material in electromagnetic field environment. Methods Based on large range of conductivity change, requirement of strong electromagnetic field motivation of adaptive intelligent electromagnetic shielding material and considering strong electromagnetic field generation of testing system, large dynamic range, precision, corresponding insulation and high safety requirement, the capacitance charge-discharge principle was adopted to design a test circuit for strong electromagnetic field motivation and create a insulation environment to guarantee safety of operation and reliability test data. Results The characteristic curve obtained in the verification test on commercial resistor with the testing system was in line with the theory. Conclusion The testing system meets the demands of phase transition property test on adaptive intelligent electromagnetic shielding material and can obtain effective and reliable test data.. |
