| Abstract: | The cutoff frequencies of direct current injection in a TEM cell is calculated by employing the point-matching method, the relation between dimensions of direct current injection device and cutoff frequencies, and the inverse ratio between the cutoff frequencies and the characteristic impedance, are presented in this paper. By experimential test and computer simulation, the application scope of direct current injection technique into electromagnetic compatibility test is evaluated. The results show that the direct current injection technique may be used under 400MHz. |
