Unshielded Two-Wire Circuit Systems under Weak Unbalance for High-Intensity Radiated Field Radiated Susceptibility by Double Bulk Current Injection
Round 1
Reviewer 1 Report
Authors should refer to the following in the manuscript:
1. For what kind of high-intensity electromagnetic radiation (HIRF) (sinusoidal?, pulsed?) is the proposed method of using DBCI applicable for the HIRF (RS) radiation susceptibility test of unshielded two-wire circuits?
2. If the proposed method is suitable for sinusoidal HIRF, in which frequency range can it be applied?
3. Since the most likely intentional EM interference (EM attack) would be in the form of short, high-intensity EM pulses, is the proposed method (using DBCI) applicable to the EM susceptibility test of unshielded two-wire circuits?

Reviewer 2 Report
The manuscript presents a rigorous solution for substituting DBCI for the HIRF electromagnetic radiation for unshielded two-wire circuit systems. The manuscript is interesting and the results are novel. The authors validated their results by measuring. I recommend it for publication with some major comments:
1 –The exact contribution should be highlighted more to distinguish it from the other works. What is the novelty of this paper in contrast with the following author's paper?
Sun, Jiangning, et al. "Test Method of Bulk Current Injection for High Field Intensity Electromagnetic Radiated Susceptibility Into Shielded Wire." IEEE Transactions on Electromagnetic Compatibility 64.2 (2021): 275-285.
2- What does the current paper add to the subject area compared with other published studies.
3- There is no information on how the article is organized at the end of the Introduction section.
4- The flow chart in Figure 5 is not complete.
5-Page 5 Line 174, 175: please explain How the authors choose the capacitance to the ground of the two cables at the left end 3 pF and the right one 7 pF?
6-I think the caption of Fig.9 should be changed for (a) and (b).
7- Conclusion should be extended, and future works must be added.

Reviewer 3 Report
The authors of the paper undertook the difficult topic of analyzing the signals' propagation of systems connected by an unshielded pair of wires exposed to an electromagnetic field with a high level of radiation (HIRF). The issue is very topical and important from the point of view of the security of military or aviation systems. In the past, cases of air crashes caused by HIRF interference can be found.
The method of linear extrapolation of the excitatory signal source proposed in the article seems to be an interesting alternative to be used in conditions where the generation of fields with intensity above several hundred V/m is impossible under laboratory conditions.
The results of experimental research are promising and can be an interesting alternative to the currently used solutions.
General remarks:
1. Frequency range of HIRF signals are divided into two parts: LF - to 400 MHz and HF - from 400 MHz to 40 GHz. Did you analyze your systems in HF?
2. Lines 36-37 - the authors discussed method of bulk current injection replacing HIRF radiation [2-8]- This is not recommendable citation style, must be more specific. Citation is a scientometric tool, cited papers must be putted in value or in criticism, also.
Detailed remarks:
1. Lines 78, 79, 102, 103 - please define m1 -.... m8
2. Figure 5 - flow chart is hardly understandable
3. The descriptions of the axes of figures 7 and 8 together with their legends are unreadable
