Experimental verification of magnetic near-field channeling using a helical-shaped wire medium lens
نویسندگان
چکیده
We experimentally verify that a magnetic uniaxial wire medium lens consisting of racemic array helical-shaped metallic wires may enable channeling the normal component field near-field sources with resolution well below diffraction limit over broad bandwidth. It is demonstrated can be regarded as counterpart usual lenses formed by straight wires. The experimental results are validated full-wave numerical simulations. envision proposed metamaterial have potential applications in resonance imaging, wireless power transfer, and sensing.
