Microwave Engineering Crossword Puzzle
February 7, 2016

For the sake of avid cruciverbalists amongst us, each week I create a new crossword puzzle that has a theme related to RF, microwave, electrical and mechanical engineering, mathematics, chemistry, physics, astronomy, mathematics, and other technical words. You will never be asked the name of a movie star unless he/she was involved in a technical endeavor (e.g., Hedy Lamarr). Enjoy!

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