Abstract

Metamaterials have been proved very useful for their high potential in guiding and manipulating of near fields. A theoretically revealed effect of the significant enhancement of evanescent harmonics inside a wire metamaterial slab is experimentally verified in the microwave frequency range. The phenomenon originates from resonant pumping of standing waves into which evanescent waves are converted inside the slab. We find a good agreement between experimental data, numerical simulations and theory. Also some metamaterials applications for magnetic resonance imaging system are viewed.
