1. An artificial magnetic conductor (AMC) resonant with a substantially zero degree reflection phase over at least two resonant frequency bands, the artificial magnetic conductor comprising a frequency selective surface having a plurality of Lorentz resonances in transverse permittivity at independent, non-harmonically related, predetermined frequencies different from the resonant frequency bands.
