This is the final RF Cafe Crossword Puzzle for 2021. Where has the year gone?
Thank you for being a loyal visitor! Look for two clues with asterisks (*) relative
to this theme. Otherwise, it has only words and clues related to RF, microwave,
and mm-wave engineering, optics, mathematics, chemistry, physics, and other technical
subjects. As always, this crossword contains no names of politicians, mountain ranges,
exotic foods or plants, movie stars, or anything of the sort unless it/he/she is
related to this puzzle's technology theme (e.g.,
Reginald Denny or the
Tunguska
event in Siberia). The technically inclined cruciverbalists amongst us will appreciate
the effort. Enjoy
