31. Frequency Selective Surface impedance Background: A frequency selective surface (FSS) absorbs radar waves in a designed frequency range. The crosses of the tiles of the surface26 are designed to absorb an 8 GHz (X-band) radar signal and transform it into heat. CrossLosses $308\Omega$ Backplane $+j189\Omega$ Incident radar waves ---> CrossC $-j502\Omega$ Patches CrossL $-j296\Omega$ $+j321\Omega$ Problem: If the magnitude of the impedance is near $377 \Omega$, it absorbs the radar waves effectively. What is the FSS's impedance at this frequency?
