We report a clear enhancement of the E-plane while the H-plane remains almost unaltered when either 1 or 4 layers are inserted. We link the results with the current density excited in the output face of the perforated structure along with the backward propagation supported by the Extraordinary Transmission Metamaterial.enginfo:eu-repo/semantics/restrictedAccessconference output10.1109/MMS.2009.5409802Extraordinary transmissionMetamaterialHardware and ArchitectureElectrical and Electronic EngineeringElectronic, Optical and Magnetic Materialshttp://www.scopus.com/inward/record.url?scp=77950328275&partnerID=8YFLogxK
