What is (S’73-M’76-SM’81-F’87) in author biography? What does (S’73-M’76-SM’81-F’87) mean in author biography. I am writing a paper and the format given for author biography also include a must fill entry: (S’73-M’76-SM’81-F’87). I tried to Google it and I can see many similar entries in authors biographies in published papers.

Can someone please help me about how to fill up the field (S’73-M’76-SM’81-F’87) for myself?
Disclaimer: I base my answer on my familiarity with the IEEE. Other societies may follow similar conventions.

For members of the IEEE, the notation in your example is a "shorthand" way for indicating when the author achieved a certain membership status within the society. For example,


  (S’73-M’76-SM’81-F’87)


means that A. N. Author became a Student Member (S) in 1973, a Member (M) in 1976, a Senior Member (SM) in 1981, and an IEEE Fellow (F) in 1987. 

If you are not a member of the IEEE, then you do not use this shorthand in your biography.
