RF Cafe Science & Engineering Crossword Puzzle
March 8, 2020

As with my hundreds of previous science and engineering-themed crossword puzzles, this one for March 8, 2020, contains only clues and terms associated with engineering, science, physical, astronomy, mathematics, chemistry, etc., which I have built up over nearly two decades. Many new words and company names have been added that had not even been created when I started in the year 2002. You will never find a word taxing your knowledge of a numbnut soap opera star or the name of some obscure village in the Andes mountains. You might, however, encounter the name of a movie star like Hedy Lamarr or a geographical location like Tunguska, Russia, for reasons which, if you don't already know, might surprise you.

cruciverbalist: [noun]  cruci- ("cross") +‎ verbal ("words") +‎ -ist ("agent, person") -- A person who constructs or works crosswords.

Reproduction of this puzzle without the express permission of RF Cafe is prohibited.

acr. = acronym, abbr. = abbreviation, pl. = plural, wds. = words

    Kirt Blattenberger,


RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
