An example of suppression of spurious stop-bands of EBG band-stop filter
(Udruženje za mikrotalasnu tehniku i tehnologiju i IEEE MTT-S Chapter-a Srbije, Beograd, 2011)
Based on the well known theory of infinite periodic structures, analytical theory of EBG (electromagnetic band gap) cells suppressing 6 higher (spurious) stop-bands is developed. Using such cells in a cascade the ...
