| Abstract: | With the wide use of dielectric material in electronic field,it is essential to exactly know the electromagnetic parameter value and to judge the effect of dielectric material in electromagnetic field.This testing system mainly tests the musters by using waveguide testing system,and mathematically calculates the electric constants through MATLAB software programming and controls the interface by VB programming language.The result of multimeasurements on the musters proves the correctness of the theoretical deduction. |
