Single-layer MM, and results of EM-wave transmission spectrum in 4–16 GHz.
(a) Mimetic diagram of designed MM and meta-atom. In simulation, the incident EM wave of electric field (E) parallel to y axis, and magnetic field (H), parallel to x axis propagates in the direction of k vector, parallel to z axis. (b) Transmission spectrum for single-layer MM hyper-transmitter. Transmission around 14.6 GHz is higher than 100% in both the simulation and the experiment. (c) Simulation on 3-dimensional EM wave pattern for single-layer MM. EM waves passing through the sample are gathered around 30λ.
