Dear Anurag Sharma

First, try searching on academic databases like Google Scholar, IEEE Xplore, or Scopus. Just type in keywords that match your design. This can help you see if something similar is out there. But don’t stress too much if you find something—sometimes, slight overlaps happen, and your approach might still be novel.

Another thing you could do is use a plagiarism checker like Turnitin or iThenticate. They’re usually used to check if something’s copied, but they can also help you see if parts of your work resemble any existing papers. It's a good way to be sure your design hasn’t been unintentionally mirrored elsewhere.

Lastly, ask a colleague or a mentor to look at your work. They might have seen something similar or can offer advice on positioning your paper differently for the next submission.

Presentation is just as important as content. A well-presented paper can significantly affect how your work is perceived. Good luck!
