Abstract
Novel tunable low-loss Frequency Selective Meta-Surfaces are presented, operating at around 15GHz. The proposed multi-layer Frequency Selective Meta-Surfaces (FSmS) exhibit significant tuning of their pass-band response with low losses employing bender piezoelectric actuator. The FSmS consist of three closely spaced periodic arrays of sub-wavelength non-resonant elements, namely an array of metallic square loops placed between two arrays of square apertures in metallic sheets, separated by air cavities. The combination of the square loop array and one of the square aperture arrays produces a High Impedance Surface response which is tuned using the piezoelectric actuators. This in turn alters the resonance condition of the complete FSmS structure and thus the central frequency of the pass-band. The structures have been investigated through simulations, achieving a frequency tuning range of 13.3%.
