Multi-Layered Arrays of Conducting Strips: Switchable Photonic Band Gap Structures
S. L. Prosvirnin and S. Zouhdi
A numerical analysis of reflecting and transmitting properties of multi-layered structures composed of doubly periodic arrays of metallic strips is presented in this paper. Array elements have been selected having the shape of the capital letters C, S and . The metallic strips of arrays are placed on a thin dielectric substrate. These strips may include a concentrated impedance loading. The interferences in the multi-layered array systems, due to multiple reflections of waves between the layers, combined with the resonance properties of single layers lead the structure to acquire typical properties of the photonic band gap (PBG) crystals.
