Angle of Incidence-Stable FSS with DSRS Elements
Abstract
A thin screen FSS with the double square ring slot (DSRS) element is proposed and demonstrated for a dual band spatial filter exhibiting closely separated pass and stop bands. The calculated band-separation-ratio is 1.15. Further, the predicted FSS transmission performance shows excellent stability with the incident angle from normal to 45° and for both TE and TM polarizations.
