Tips for preparing a search: Keep it simple - don't use too many different parameters. Separate search groups with parentheses and Booleans. Note the Boolean sign must be in upper-case. One the most successful polarimeters is the dual rotating retarder polarimeter ( DRR ), invented by Azzam in 1978.
