Research on Desktop Wide Range Wireless Power Transfer Based on High Frequency Electric Field
Round 1
Reviewer 1 Report
The paper presents a desktop wireless energy transfer system with possible applications in the case of very low power portable electrical equipment.
The manuscript should be carefully reviewed, clarifications and additions are necessary.
How does the proposed wireless power transfer system differ from other existing systems in the literature? Authors should highlight their contribution. The results should be presented compared to other wireless power transfer systems.
What was the maximum value of the transferred power in the case of experimental platform? How was the transferred power determined? Was it measured or calculated?
References [4-16] are missing from the main text. References should be numbered in order of appearance and indicated by numerals in square brackets.
Please correct: "Figure5, Figure6, Figure7, Figure8".

Point 1: How does the proposed wireless power transfer system differ from other existing systems in the literature? Authors should highlight their contribution. The results should be presented compared to other wireless power transfer systems.
Response 1: Thank you very much for your valuable suggestions. In the abstract and introduction, the difference between this wireless power transmission system and other existing systems is explained. The advantage is that it is easier to build, the power receiving device is smaller, and it can wirelessly supply power to handheld electrical equipment.
Point 2: What was the maximum value of the transferred power in the case of experimental platform? How was the transferred power determined? Was it measured or calculated?
Response 2: The specific data and calculation method of the experimental transmission power have been supplemented in the article.
Point 3: References [4-16] are missing from the main text. References should be numbered in order of appearance and indicated by numerals in square brackets.
Response 3: The references have been revised in accordance with the regulations.
Point 4: Please correct: "Figure5, Figure6, Figure7, Figure8".
Response 4: Optimized the pictures in the paper. The latest manuscript has been uploaded. I would like to express my sincere thanks again.

Reviewer 2 Report
- The abstract is short and insufficient, you must expand it,
- Likewise, the intro section is verbose and does not communicate the paper well. Where are the contributions list? What is the motivation and research issue….etc
- The equations used are very vague and you need to elaborate on each thoroughly.
- Evaluation is good, but the plots need some captions on the y-axis please.
- Change the title of Sec 6 to Conclusions and Future Work.

Reviewer 3 Report
The paper Research on Desktop Wide Range Wireless Power Transfer Based on High Frequency Electric Field is focused on experimentation with wireless power transmission based on high frequency electric field. The authors theoretically proposed and experimentally verified the application of aluminum foil plate as a power transmitter together with LC resonant circuits.
First, the language level throughout the entire paper is somewhat acceptable, however, I notices several mistakes during reading the text, therefore I recommend to perform minor language editing and proofreading.
Generally, the paper is well organized containing both theoretical and practical sections, the paper is technically sound and the adopted methodology is acceptable.
Some acronyms are not well explained, e.g. DWPT, etc.
There are no proper SI units used in Y-axes description in Fig. 10, 11 and 12.
I miss any information about EMC problems caused by radiation of electromagnetic field of the proposed solution. I think the presented solution creates unnecessary electromagnetic radiation in a wide area around the aluminum desk causing EMC problems and disturbances. I think authors should address and discuss this problem.
I think the paper should also contain a discussion of the efficiency of the energy transfer capabilities of the proposed solution. The authors presented the theoretical efficiency of 46%, however, the experimentation provided the energy transmission efficiency of only 15%. Is there any possibility to increase the efficiency in practice? Please provide some comparison of the efficiency of your solution and similar existing solutions presented in your references.

Point 1: Some acronyms are not well explained, e.g. DWPT, etc..
Response 1: Thank you very much for your valuable suggestions. Explains the meaning of the abbreviations in the text.
Point 2: There are no proper SI units used in Y-axes description in Fig. 10, 11 and 12.
Response 2: The pictures in the text have been modified.
Point 3: I miss any information about EMC problems caused by radiation of electromagnetic field of the proposed solution. I think the presented solution creates unnecessary electromagnetic radiation in a wide area around the aluminum desk causing EMC problems and disturbances. I think authors should address and discuss this problem.
Response 3: The electromagnetic interference problem is supplemented in the electromagnetic field simulation. When wireless power is supplied to low-power electrical equipment, the leakage electromagnetic field of the system is relatively weak.
Point 4: I think the paper should also contain a discussion of the efficiency of the energy transfer capabilities of the proposed solution. The authors presented the theoretical efficiency of 46%, however, the experimentation provided the energy transmission efficiency of only 15%. Is there any possibility to increase the efficiency in practice? Please provide some comparison of the efficiency of your solution and similar existing solutions presented in your references.
Response 4: The problem of transmission efficiency is discussed, and solutions are proposed, which will be improved in future research. The latest manuscript has been uploaded. I would like to express my sincere thanks again.
