Due respect is paid throughout this technically themed crossword puzzle to the
Greek letter "Xi," which has been dissed by the World Health Organization by
omitting it from the succession of designations for new COVID−19 variants (look
for an asterisk after the clue). Xi has been restored to its rightful place as the
14th letter in the Greek alphabet. Only clues and words are directly to RF, microwave,
and mm-wave engineering, optics, mathematics, chemistry, physics, and other science
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!
