Abstract
According to various aspects, exemplary embodiments include one or more frequency selective surfaces, which may be used for attenuating, reflecting, and/or redirecting electromagnetic signals. Also disclosed are methods of using one or more frequency selective surfaces for attenuating, reflecting, and/or redirecting electromagnetic signals.
Claims20
A structure comprising a frequency selective surface including electrically-conductive members and electromagnetic energy absorptive members coupled to the electrically-conductive members, whereby the frequency selective surface is operable for attenuating electromagnetic signals within a cavity of a closed structure when the frequency selective surface is positioned within the cavity to thereby reduce cavity resonance and/or electromagnetic energy propagation within the cavity.
A cavity resonance reduction and/or shielding structure comprising a frequency selective surface including:
- electrically-conductive members configured to resonate at one or more bandstop frequencies;
- and
- electromagnetic energy absorptive members coupled to the electrically-conductive members;
- whereby the frequency selective surface is operable for attenuating electromagnetic signals at the one or more bandstop frequencies within a cavity of a closed structure when the frequency selective surface is positioned within the cavity.
A method comprising positioning a frequency selective surface within a cavity of a closed structure such that electrically-conductive members and electromagnetic energy absorptive members of the frequency selective surface are operable for attenuating electromagnetic signals within the cavity, to thereby reduce cavity resonance and/or electromagnetic energy propagation within the cavity.
