研究目的
To present a modeling technique to speed up the evaluation of radiated fields from interconnect cables based on the Hertzian dipole radiation theory and transmission-line frequency-dependant solutions.
研究成果
The proposed modeling technique provides a faster solution with less computing resources for evaluating radiated fields from interconnect cables. It has been verified by open-line and RG 58 coaxial cable measurements, showing good agreement between the model and the measurement.
研究不足
The method's accuracy may be affected by the artifacts introduced by the current probe, scattering from the termination plates, laboratory objects, etc., which were not considered in the model.
1：Experimental Design and Method Selection:
The method involves modeling the radiating source by the sum of a large number of short dipoles based on Hertzian dipole radiation theory and transmission-line frequency-dependant solutions.
2：Sample Selection and Data Sources:
The method is verified by open-line and RG 58 coaxial cable measurements.
3：List of Experimental Equipment and Materials:
Equipment includes a vector network analyzer for measuring line-end discontinuities and antennas for field measurements.
4：Experimental Procedures and Operational Workflow:
The line-end discontinuities are characterized by fitting to the measured impedance curve from a cable prototype. The radiated field is then calculated using the method of small Hertzian dipoles.
5：Data Analysis Methods:
The calculated results of the radiated emissions are compared with the measurement results using antenna measurements.
